GAM stands for Generalized Additive Models. The canonical reference for the methodology and software is the book by Breiman, Friedman, Olshen and Stone, Classification and Regression Trees from Wadsworth Press. As the name implies, the CART methodology involves using binary trees for tackling classification and regression problems. CARTĬART stands for Classification and Regression Trees. Implementations now exist in many software packages including a very flexible one in the boot package in R. ![]() "Bootstrap" means that one available sample gives rise to many others by resampling (a concept reminiscent of pulling yourself up by your own bootstraps). Bootstrap technique was invented by Bradley Efron (1979, 1981, 1982) and further developed by Efron and Tibshirani (1993). The bootstrap method estimates the standard error of a statistic by repeatedly drawing "bootstrap samples" from the original data, re-evaluating the statistic for each bootstrap sample, and estimating the standard error of the original statistic by the observed variability in the bootstrap statistic values. ![]() Our faculty have been active both in developing statistical methodologies and in implementing software applications based on those methodologies.
