PCA and exploratory Factor Analysis on the same dataset: …
Splet02. okt. 2024 · The most widely-used method of extraction in factor analysis is the principal axis factoring (PAF) method. The method seeks the least number of factors which can account for the common variance of a set of variables. In practice, PAF uses a PCA strategy but applies it on a slightly different version of the correlation matrix. Splet11. maj 2024 · Below I will do, step by step, Principal Component analysis (PCA) of iris data ("setosa" species only) and then will do Factor analysis of the same data. Factor analysis (FA) will be done by Iterative principal axis ( PAF) method which is based on PCA approach and thus makes one able to compare PCA and FA step-by-step.
