PCA Tutorial using SIMCA

This video provides a tutorial in how to perform Principal Components Analysis (PCA) using SIMCA 14.1. All the basic functionality of SIMCA is explored using an example spectroscopic dataset. The dataset is MIR spectra of fresh meats, sourced from https://csr.quadram.ac.uk/example-dat... "120 Mid-infrared (MIR) spectra of fresh minced meats – chicken, pork and turkey. Duplicate acquisitions from 60 independent samples. Raw data matrix size [448 x 120]. Obtained using Fourier transform infrared (FTIR) spectroscopy with attenuated total reflectance (ATR) sampling. As described in “Mid-infrared spectroscopy and authenticity problems in selected meats: a feasibility study“ Al-Jowder O, Kemsley E K, Wilson R. H.(1997) Food Chemistry 59 195-20. More on our food authentication work." The original publication can be found here, for comparison https://www.sciencedirect.com/science... SIMCA is software from Umetrics, now Sartorius Stedim Biotech. https://umetrics.com/products/simca
