ab: From the editorial: The article continues the author\rq s History of
mathematics series. In this article he considers factor analysis
applied to test scores. The underlying idea in factor analysis is to
determine if a number of observables $y_1,y_2,\dots ,y_n$ can be
linearly related to a smaller number of unobservable factors
$f_l,f_2,\dots ,f_k$. For example the observables might be scores from
many different students in $n$ different tests.
