Abstract: The present invention provides relatively robust comparison of bioinformatic data, such as gene expression data, by providing a computer-implemented method, a computer program product and a computer readable medium, that analyzes data according to the appended patent claims. The invention provides stability with respect to re-sampling of data.

Abstract: A computer-implemented method for analyzing multivariate data comprising a plurality of samples of each of a plurality of measurement variables is disclosed. The method comprises, for a first subsetA (X) of the multivariate data X, determining (110) a first projection score related to the first subset. Furthermore, the method comprises, for a second subsetB (X) of the multivariate data X, determining (120) a second projection score related to the second subset. Moreover, the method comprises, comparing (130) the first and the second projection score for determining which one of the first and the second subset provides the most informative representation of the multivariate data, which is defined as the one of said subsets having the highest related projection score. A definition of the projection score is also provided.
