Glms explained
Webby David Lillis, Ph.D. Last year I wrote several articles (GLM in R 1, GLM in R 2, GLM in R 3) that provided an introduction to Generalized Linear Models (GLMs) in R.As a reminder, Generalized Linear Models are an extension of linear regression models that allow the dependent variable to be non-normal. In our example for this week we fit a GLM to a set …

For some Poisson and binomial GLMs, the number of observations N stays fixed as the individual counts increase in size. Then the deviance has a chi-squared asymptotic null distribution. umpire camps in michiganWebGLMs are actually pretty powerful. You can do nonlinear models in X via GLMs, because linearity is only in the beta coefficients. Also the fancy ML models are simply just “adaptive GLMs” in disguise.
