you can find some popular Data Mining algorithms in STAT, such as KNN, LDA, CDA, various regression models, (regularized) Logistic, LASSO (v9.2), disjoint partition clustering and hierarchical clustering, SVD&PCA, Bagging, etc.
With some tweak, you can also implement algorithms such as AdaBoost, LSI & vector space model in TextMining, the efficiency is not on par with EM, though. consult my blog for more:

You get extra that is not available in STAT, such as Neural Network, CART, etc
