Instability of statistical factor analysis [PDF]

open access: yesProceedings 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 \(\mathbb{R} ^{p}\).
