NNRV-HICLAS
Introduction
Description
The nonnegative real-valued model of hierarchical classes (NNRV-HICLAS) software allows to fit nonnegative real-valued hierarchical classes models to two-way two-mode data (e.g., a rectangular objects by attributes data matrix). Given such data, the NNRV-HICLAS program performs nonnegative real-valued hierarchical classes analyses of a prespecified complexity (i.e., number of object and attribute clusters) by means of a multi-start two-stage algorithm combining a simulated annealing and an alternating local descent stage. The NNRV-HICLAS program is available in MATLAB.
Authors
The NNRV-HICLAS program was created by Jan Schepers of the Research Group of Quantitative Psychology and Individual Differences of the Katholieke Universiteit Leuven.
