Research on the Cognition and Application of Multivariate Statistical Analysis Models

Multivariate statistical analysis is the use of mathematical models and statistical theory to study multivariate problems. Based on Bloom's cognitive theory, according to the learner's learning process, the cognitive process of multivariate statistical analysis can be divided into multivariate statistical models, behavioral characteristics of multivariate statistical analysis, and applications of multivariate statistical analysis. The application of principal component analysis in water quality evaluation is taken as the research object, and the cognitive process of multivariate statistical analysis is specifically demonstrated.
