Generalized Principal Component Analysis: Transcript

René Vidal Center for Imaging Science Institute for Computational Medicine Johns Hopkins University Data segmentation and clustering Given a set of points separate them into multiple groups Discriminative methods learn boundary. When applied to generalized l inear models multilevel models and other extensions of classical regression ANOVA can be e xtended in two di64256erent directions First the Ftest can be used in an asymptotic or approximat e fashion to compare nested mo SPSS.
