FlexMix implements a general framework for fitting discrete mixtures of regression models in the R statistical computing environment: three variants of the EM algorithm can be used for parameter estimation, regressors and responses may be multivariate with arbitrary dimension, data may be grouped, e.g., to account for multiple observations per individual, the usual formula interface of the S language is used for convenient model specification, and a modular concept of driver functions allows to interface many different types of regression models. Existing drivers implement mixtures of standard linear models, generalized linear models and model-based clustering. FlexMix provides the E-step and all data handling, while the M-step can be supplied by the user to easily define new models. Minimize

| A new ensemble method for cluster analysis is introduced, which can be interpreted in two dierent ways: As complexity-reducing preprocessing stage for hierarchical clustering and as combination procedure for several partitioning results. The basic idea is to locate and combine structurally stable cluster centers and/or prototypes. Random eects of the training set are reduced by repeatedly training on resampled sets (bootstrap samples). We discuss the algorithm both from a more theoretical and an applied point of view and demonstrate it on several data sets. Keywords| cluster analysis, bagging, bootstrap samples, k-means, learning vector quantization I. Introduction Clustering is an old data analysis problem and numerous methods have been developed to solve this task. Most of the currently popular clustering techniques fall into one of the following two major categories: Partitioning Methods Hierarchical Methods Both methods have in common that they try to group the data s.
