WebJun 15, 2024 · Introduction. Multivariate regression is a major approach of chemometrics [1] and consists in defining a relationship between a set of independent variables and a quantitative response. The response is considered as the interesting element of the system under analysis, such as the concentration of analytes or the biological activity of chemicals.
