The proceedings contain 49 papers. The topics discussed include: principal component analysis for categorical histogram data: some open directions of research; factorial conjoint analysis based methodologies; ordering and scaling objects in multivariate data under nonlinear transformations of variables; statistical models to predict academic churn risk; the Poisson processes in cluster analysis; efficient incorporation of additional information to classification rules; the choice of the parameter values in a multivariate model of a second order surface with heteroscedastic error; mixed mode data clustering: an approach based on tetrachoric correlations; optimal scaling trees for three-way data; a study on text modeling via dirichlet compound multinomial; automatic multilevel thresholding based on a fuzzy entropy measure; and spectral graph theory tools for social network comparison.
