Abstract. SIMCA-P is a kind of user-friendly software developed by Umetrics, which is mainly used for the methods of principle component analysis (PCA) and partial least square (PLS) regression. This paper introduces the main glossaries, analysis cycle and basic operations in SIMCA-P via a practical example. Correspondingly, 2 versions of PLS-DA are presented: the conventional hard PLS-DA, and the newly introduced soft PLS-DA that seems to be a novel approach in chemometrics. The quality of classification is assessed using the figures of merit (sensitivity, specificity, and efficiency). It is shown how these characteristics are used for the SIMCA ® combines its powerful multivariate engine with interactive visualizations, an intuitive interface, and the ability to automate workflows—for truly user-friendly software that eases your analytical workload from start to finish: Import data from multiple file formats.
