Abstract Software for the analysis of multivariate chemical data by principal components and partial least squares methods is included on disk. The methods extract latent variables from the chemical data with the UNIversal PArtial Lease Squares (UNIPALS) algorithm. The software is written in BASIC, provides a number of editing and preprocessing options and is interactive. The method provided here is limited to the analysis of 20 x 20 matrices. It contains options for the graphical display of scores and loadings for interpretation of the results of analyses. (Copyright (c) 1990 Pergamon Press plc.)
