Statistical Software SAM II : Sensitivity Analysis in Multivariate Methods

The statistical software SAM II which is a revised version of SAM is designed to make sensitivity analysis in descriptive multivariate analysis. This program has the unified formulation of sensitivity analysis for any multivariate methods formulated as eigenvalue problems by using generalized singular value decomposition. In this program there are three steps; (1) pre-processing, (2) original analysis and (3) sensitivity analysis. By this revision, the number of multivariate methods to be treated are increased, the displays of the influences of individuals on the results of analysis are improved and the influence of not only a single individual but also multiple individuals can be observed.
