A note on factor congruence

A nonheuristic methodology for studying the stability of factor structures and computer simulation results are reported The results indicate that a highly conservative lower limit to the Burt-Tucker-Wrigley-Neuhaus coefficient of factor congruence, greater than 0. [...]this index only tests pairs of factors not factor spaces. Computer simulations under various similarity and dissimilarity conditions were performed to examine P( SI psi^sub 1^ == psi^sub 2^ ) and derive a nonheuristic value, delta^sub c^ such that delta >delta^sub c^ is sufficient to conclude that a factor space as well as individual factors are congruent.
