  • It increases the risk of getting cancer! Your sentence implies that you get it each time you are exposed. However, there is a subtle difference between being really attacked by a lion or being in the territory of a lion. In the first case you are highly likely done, in the second you have a chance to get out complete and healthy. And also: when and how are often two important questions.

    Why I am saying this: I knew two guys in my family, who smoked from young like chimneys. They died old (>90) and not due to lung cancer! But perhaps in their times (50-90) the cigarettes were less toxic, who knows 🤷‍♂️













  • AFAIR the R2 is (almost) equal to rho in the Pearson correlation. I just see two variables, a linear fit from - possibly - an OLS. The small R2 is likely due to the outlier (though a single outlier by this mass of points raises my eyebrows as the MSE (or take the RSME) won’t be affected as such by a single point when there are 15’000 points centered closely around an estimate, but CCV would tell) and R2 says nothing about the p-value, which is determined by the amount of information in a system/about variables, and hence likely way below 0.05.

    This relationship aka in this case correlation says pretty much nothing about real world, because IQ is (possibly) not only determined by IQ, but way many other factors. The picture is utterly simplified. It is similar to the relationship between the number of babies and the number of storks.







  • You should be careful to tackle the gaming community. There are many nerds and script kiddies who are well connected and who have little troubles to make your life less happy. Something which did not exist in the Eastern block, and especially not in Eastern Germany - remember: it wasn’t Eastern Germany where the revolts started against the regime! They just jumped on the train. Not few Eastern Germans are dreaming nowadays to have something like the German Democratic Republic back.
