Vintage factor analysis with Varimax performs statistical inference [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2023 Abstract In the 1930s, Psychologists began developing Multiple-Factor Analysis to decompose multivariate data into a small number of interpretable factors without any a priori knowledge about those factors. In this form of factor analysis, the Varimax factor rotation redraws the axes through the multi-dimensional factors to make them ...

Instability of statistical factor analysis [PDF]
Proceedings of the American Mathematical Society, 2004 Summary: Factor analysis, a popular method for interpreting multivariate data, models the covariance among \(p\) variables as being due to a small number (\(k\), \(1 \leq k < p\)) of hidden variables. A factor analysis of \(Y\) can be thought of as an ordered or unordered collection, \(F(Y)\), of \(k\) linearly independent lines in \(\mathbb{R} ^{p}\).
