Factor Analysis for Clustered Observations.

Longford, N. T.; Muthen, B. O.

Psychometrika, v57 n4 p581-97 Dec 1992

A two-level model for factor analysis is defined, and formulas for a scoring algorithm for this model are derived. A simple noniterative method based on decomposition of total sums of the squares and cross-products is discussed and illustrated with simulated data and data from the Second International Mathematics Study.
