(27,28) Basis splines are a type of generalized additive model (GAM), where a smooth curve is computed based on the sum of low-order polynomial basis functions joined at k control points. We describe the theoretical connection between HGAMs, HGLMs, and GAMs, explain how to model different assumptions about the degree of intergroup variability in functional response, and show how HGAMs can be readily fitted using existing GAM software, the mgcv package in R. His post reminded me of another excellent blog entry by Antonio Piccolboni where he used the page. Last week, I had the opportunity to talk to a group of Master’s level Statistics and Business Analytics students at Cal State East Bay about R and Data Science.
