by Joseph Rickert Generalized Linear Models have become part of the fabric of modern statistics, and logistic regression, at least, is a “go to” tool for data scientists building classification applications. The ready availability of good GLM software and the interpretability of the results logistic regression makes it a good baseline classifier. Moreover, Paul Komarek argues that, with a little bit tweaking, the basic iteratively reweighted least squares algorithm used to evaluate the maximum likelihood estimates can be made robust and stable enough to allow logistic regression to challenge specialized classifiers such as support vector machines. It is relatively easy...
