Abstract: | Asymptotic distributions of the estimators of communalities are derived for the maximum likelihood method in factor analysis.
It is shown that the common practice of equating the asymptotic standard error of the communality estimate to the unique variance
estimate is correct for standardized communality but not correct for unstandardized communality. In a Monte Carlo simulation
the accuracy of the normal approximation to the distributions of the estimators are assessed when the sample size is 150 or
300.
This study was carried out in part under the ISM Cooperative Research Program (90-ISM-CRP-9). |
