So the mean is three,Īnd this is one sample standard deviation for y above the mean and this is one standardĭeviation for y below the mean. We could do the same thing for the y variables. Sample standard deviation below the mean, and then Sample standard deviation above the mean, this is one Is eight divided by four, which is two, so we have xĮquals two right over here. One plus two plus two plus three divided by four, Here, so the sample mean for x, it's easy to calculate In red so that you know that's what is going on Sample standard deviation for x are here in red, and actually let me box these off We clearly have the fourĭata points plotted, but let's plot the statistics for x. So before I do that, let's just visualize some of the statistics that we have here for these data points. On this video is build on this notion and actuallyĬome up with the equation for the least squares We got an r of 0.946, which means we have a fairly If r is equal to zero, you don't have a correlation, but for this particular bivariate dataset, One, you have a perfect negative correlation, and And as we said, if r is equal to one, you have a perfect positive correlation. The product of the z scores for each of those pairs. In that video we saw all it is is an average of In previous videos, we took this bivariate data and weĬalculated the correlation coefficient, and justĪs a bit of a review, we have the formula here, and it looks a bit intimidating, but This has applications in machine learning and AI - FYI. Wouldn't have thought about it and was going to skip this video. So we substitute the m, Xmean, Ymean, and then get Y intercept. We know for a fact that for the regression line function, we have Xmean and Ymean as part of its points or at its intersection. But the r also factors into this calculation. Then he shows that rise over run, which is slope, is equal to Sy/Sx. And then he draws 1 stddev lines for x and y axis. They have also provided x,y mean and stddev.įirst they use the Xmean and Ymean as reference. He shows formula to get the correlation coefficient, but they have already done all the calculation to get the best correlation coefficient. Goal is to find regression line that best fits the data point.

While the name Steve originated as a joke from Persson due to being "generic", the name was adopted by the community and became official in the Bedrock Edition of Minecraft. In console edition of the game, Steve was presented in a variety of different outfits, such as a tuxedo, a prison outfit, and an outfit based on Scottish attire. His design consists of a light blue top, a pair of blue trousers, and shoes, while his face is a eight-by-eight pixel image usually adorned with a goatee. He is presented as a human character with a blocky appearance, which is consistent with the aesthetic and art style of the game. Steve was designed for Minecraft by the game's creator Markus Persson. Steve's design has additionally been utilized in unofficial media, such as the " Herobrine" creepypasta. Subsequently, he has been frequently banned from several tournaments for the game. Ultimate, where he is ranked as the games best character and has sparked controversy due to his power. In October 2020, Steve was added as a playable character to Super Smash Bros. Considered by some critics as a mascot for the Minecraft intellectual property, his likeness has appeared extensively in advertising and merchandise, including wearable apparel and collectible items. Steve became a widely recognized character in the video game industry following the critical and commercial success of the Minecraft franchise. Depending on the version of Minecraft, players have a chance of defaulting to either Steve or any of the other variant skins when creating a new account, although the skin is easy to change from the client or website. His feminine counterpart, Alex, was first introduced in August 2014 for Java PC versions of Minecraft, with the other seven debuting in the Java edition of the game in October 2022. Steve lacks an official backstory by the developers of Minecraft as he is intended to be a customizable player avatar as opposed to being a predefined character. Created by Swedish video game developer Markus "Notch" Persson and introduced in the initial Java-based version of Minecraft which was first publicly released on May 17, 2009, Steve is one of nine default player character skins available for players of contemporary versions of Minecraft.

Flat engraving is done by setting the laser to a lower power, and the results are quite crisp. Some flames can appear during cutting, but they generally extinguish themselves quickly.Įngraving is also possible. Eighth of an inch plywood cut in a single pass at 20% power and 15 mm/s, and a quarter of an inch cut at 25% power at the same 15 mm/s. Woods are easily cut, the laser has no problem cutting through birch plywood in a single pass. I found those were a good starting point. The instruction manual goes pretty indepth with what materials can be used, and even gives recommended speeds and feeds for many common thicknesses of materials. Mine did need to be adjusted, so after about 30 minutes, the mirrors were fully aligned and it’s time to cut! Materials The steps are all listed in the instructions, and each mirror has 3 spring-loaded screws used to adjust the position. You will have to remove some glue to adjust the mirrors. Globs of hotglue are used all over the machine, holding down the mirror alignment nuts, attaching the LED light strip in the interior, and holding connectors on the control board. The mirrors may shift during shipping, so you should check the alignment before you start cutting. I purchased a window insert and connected the exhaust ducting so that it vents outside. You will also need somewhere to vent the exhaust. I used a 5 gallon plastic bucket and cut some holes in the top for the tubing. You will need to purchase a container to hold water and the pump. It comes with the machine, a water pump, venting duct, usb cable, usb flashdrive, and a usb key for the LaserDRW program. The machine ships pre-assembled in a box weighing about 70 pounds. The workflow using Inkscape and K40 Whisperer took a little bit of time to get used to, but once past the initial learning curve it was simple to create a file and send it over to the laser. A usb dongle with the LaserDRW license is supplied with the laser, more on that in a bit, but I grew to prefer using K40 Whisperer. That makes it easy to see if the laser is getting too hot which will reduce it’s expected life.Īs for software, the Monport 40W supports LaserDRW and K40 Whisperer. It also has two temperature gauges showing the tube temperature and the power supply temperatures. The front panel of the laser contains the main power switch, a locking emergency stop switch, as well as a digital readout and controls for the laser power percentage. There is no way to store a cut file on the laser itself, it needs to always be connected to a computer. The board connects to a computer via the USB port, and the computer is what sends the laser the instructions to cut. The stepper motors are controlled by a Studio Labs m2 Nano 8-bit control board. The focus is set 2” between the lens and the top of the cutting board, and if you need to adjust focus you’ll have to raise or lower the material. The gantry moves in the x and y axis, but there is no z-axis adjustment for the focus. The machine has a built-in exhaust fan, which vents out the back of the machine through the included 4” ducting. The cutting board is easily cleaned, wiping it down with isopropyl alcohol cleans off any debris. The clamp can be helpful if you need to repeatedly position material, but most of the time I simply laid the material on the main cutting board. It comes with a flat ventilated cutting board, the center of which can be removed to reveal a built in clamping system. The Monport 40W laser cutter has a max cut area of 8 inches by 12 inches. The laser tube has a life expectancy of 1500 to 2000 hours of operation, when used under 40% max power and kept adequately cooled. The laser tube is watercooled, and tubing and a submersible pump is included. The laser has a wavelength of 10640 nanometers, which is far into the infrared spectrum and invisible to the naked eye. The laser is generated via a water-cooled tube in the back of the machine, reflected off of the 3 mirrors on the movable gantry, and focused using a fixed 12mm lens before cutting or engraving the material placed inside of the machine. Like the name suggests, the Monport 40W CO2 laser cutter is a K40 style CO2 laser cutter with a max laser power of 40 watts. As with all my reviews, they aren’t paying for this review, and everything I say is my own honest opinion after using the machine for the last month. This 500 dollar laser cutter has all the makings of a great entry-level laser cutter on paper, but how does it fair in practice?

I have personally experienced the effects of global warming How strongly do you agree or disagree with the statement above? Global warming is affecting the weather in the United States Most scientists think global warming is not happening.There is a lot of disagreement among scientists about whether or not global warming is happening.Most scientists think global warming is happening.Most scientists think global warming is happening Which comes closest to your own view? None of the above because global warming isn’t happening.Caused mostly by natural changes in the environment.Global warming is caused mostly by human activities Assuming global warming is happening, do you think it is… ? What do you think: Do you think that global warming is happening? Global warming refers to the idea that the world’s average temperature has been increasing over the past 150 years, may be increasing more in the future, and that the world’s climate may change as a result. Global warming is happening Recently, you may have noticed that global warming has been getting some attention in the news. Individuals who responded “Don’t know” or who did not answer the question were not modeled separately and appear as gray segments within the bar charts. For example, for the question measuring how worried respondents are about global warming, “very worried” and “somewhat worried” were combined into a single measure of “worried.” Likewise “Not very worried” and “Not at all worried” were combined into a single measure of “not worried.” The responses below are color coded to indicate how they were grouped into the variables shown on the maps. The response categories for many questions were collapsed into a single variable for mapping. Model estimates in the maps were derived from public responses to the following survey questions.

The estimates are derived from a statistical model using multilevel regression with post-stratification (MRP) on a large national survey dataset (n>22,000), along with demographic and geographic population data, along with political party registration data derived from state voter files.įor more details, please see the peer-reviewed paper describing these results: Mildenberger, M., Marlon, J.R., Howe, P.D., & Leiserowitz, A. This site provides estimates of Republicans’ and Democrats’ climate change beliefs, risk perceptions, and policy preferences at the state and congressional district levels – a new source of high-resolution data on public opinion that can inform national, state and local decision-making, policy, and education initiatives.

Party registration data is available for 32 states, and is imputed in the remaining states (i.e., in Alabama, Georgia, Illinois, Indiana, Michigan, Minnesota, Mississippi, Missouri, Montana, North Dakota, South Carolina, Tennessee, Texas, Vermont, Virginia, Washington, and Wisconsin).ĭetails about the methods can be found here: The public opinion estimates were generated using a statistical model that combines nationally representative survey data gathered by the Yale Program on Climate Change Communication and the George Mason Center for Climate Change Communication between 20 with voter registration, U.S. The 2018 Partisan Climate Opinion Maps provide data about how Republican and Democratic climate and energy opinions vary across all 50 states and all 435 congressional districts, revealing spatial patterns with policy-relevant implications for the trajectory of US climate change policy reforms. Historically, our understanding of this partisan variability has been limited to analysis of national- or less commonly, state-level opinion poll subsamples. Even as US partisan polarization shapes climate and energy beliefs and attitudes, substantial heterogeneity in climate opinions still exists among both Republicans and Democrats. 2003a, b).īased on these findings, PTSD-6Y was established as a distinct diagnostic subtype in the DSM-5, mirroring the structure of PTSD-AA. Prior to DSM-5, several studies showed that this alternative algorithm (PTSD-AA) was superior to the DSM-IV algorithm in its alignment with the presence of PTSD-related clinical impairment (De Young et al. A proposal for more developmentally sensitive criteria modified the diagnostic algorithm to four symptoms only, removed the requirement for peri-event emotions, and suggested important developmental adaptations. 2001, 2005) with consequent effects for funding, and care provision. This algorithm was problematic as several symptoms from the DSM-IV avoidance cluster (e.g., a sense of hopelessness) were rarely detectable in young children, leading to under-diagnosis of the disorder (Scheeringa et al. Under DSM-IV, to receive a PTSD diagnosis, a young child must have experienced a Criterion A trauma eliciting high levels of affect, presented with at least one re-experiencing symptom, three avoidance symptoms, two arousal symptoms, and shown impaired functioning. Studies leading up to the DSM-5 revealed that PTSD was underdiagnosed in young children (Scheeringa et al. The introduction of posttraumatic stress disorder for children 6 years and younger (PTSD-6Y) in the Diagnostic and Statistical Manual, Fifth Edition (DSM-5 2013) is an important acknowledgement that stress responses of young children show developmental differences compared to adults. Although a 4-factor Dysphoria model offers a better overall account of clustering patterns (relative to alternate models), alongside acceptable sensitivity and specificity for detecting clinical impairment, it also falls short of being an adequate model in this younger age group. These CFA results do not support the symptom clusters proposed within the DSM-5 for PTSD-6Y. The 1-factor model offered the most compelling balance of sensitivity and specificity, with the 2-factor model and the Dysphoria model following closely behind. These two models also only showed small levels of convergence with CBCL dimensions. The Dysphoria and PTSD-6Y models offered the better accounts of symptom structure, although neither satisfied minimum requirements for a good fitting model. Criterion related validity was established by comparing each model to a categorical rating of impairment. Convergent validity was established against the Child Behavior Checklist (CBCL). The model was compared to DSM-IV, a 4-factor ‘dysphoria’ model that groups symptoms also associated with anxiety and depression, and alternate 1- and 2- factor models. Data for N = 284 (3–6 years) trauma-exposed young children living in New Orleans were recruited following a range of traumas, including medical emergencies, exposure to Hurricane Katrina and repeated exposure to domestic violence. This study utilized confirmatory factor analytic techniques to evaluate the proposed DSM-5 PTSD-6Y factor structure and criterion and convergent validity against competing models. A subtype of the posttraumatic stress disorder diagnosis for children 6 years and younger (PTSD-6Y) was introduced in the Diagnostic and Statistical Manual, Fifth Edition (DSM-5). |
