Genstat has many conventional statistical techniques such as generalized linear models (e.g. log-linear models and logistic regression) and multivariate analysis (e.g. canonical variates analysis and cluster analysis) that are very useful for data mining. It also provides various more specialized techniques such as association rules, classification and regression trees, random forests, k-nearest-neighbours classification, self-organizing maps, neural networks and radial basis functions.
