In the previous posts, I explained the covariate shift but missed the most important part… How can we detect it? This simple diagram is breaking down various covariate shift detection methods: 1) Multivariate - detects a shift in a joint(multiple features) distribution 2) Univariate - detects changes in a single feature distribution, using either: ↳ Statistical tests ↳ Distance methods Each of these methods has trade-offs based on the type of shift, but I will talk more about it in the next post👀

This article by John V. Kane on Medium provides an interesting but often overlooked contrast between Correlation analysis (specifically, Pearson’s pairwise correlation) and regression analysis (specifically, bivariate ordinary least squares (OLS). Major point I drew from the article is that: while correlation and regression coefficients are often seen as being similar, it is possible for two variables to show a strong correlation but actually have a weak overall effect on each other or regression. Have you encountered situations where correlation and regression analysis yielded different insights? How did you handle it? If you would like to know more about this, give it a read by following the link to this article attached to this post. https://lnkd.in/dRekMTiD

When one wants specific answers to specific questions regarding statistical power, one cannot do much better than a simulated power analysis. For instance, what does power mean for an individual coefficient in a regression, which presumably has a larger magnitude and less standard error present than other coefficients? I show at least one basic example in the link below. Other examples of similar techniques for finding term-specific power are also shown. #statistics #researchmethods #statisticalthinking https://lnkd.in/g_mnw-dg
