The following paper deals with the problem of estimating a factor matrix, when certain specified factor loadings are known or assumed in advance to be zero. Two simple procedures are proposed, the first for uncorrelated factors, the second for correlated factors. An approximate test for the significance of the residuals is also described, and the whole process illustrated by a worked example.
