خواص روان سنجی و مقایسه تکنیک های مختلف برای تجزیه و تحلیل عامل بر روی 5 انفجار بزرگ از یک نمونه فلاندی

Second, we compare the usual method of analysis, namely factor analysis with principal component extraction with varimax rotation, to several methods that each address a common problem in factor analysis. We compare the original analysis to factor analysis with a non-orthogonal rotation (addressing the problem of correlated factors), after ipsatisation (considering individual response styles), using polychoric correlations (taking into account the type of the responses), and using multiple imputation to handle missingness (to account for potential bias due to listwise deletion). The five factor analyses do not differ substantially. However, the analysis using polychoric correlations has the highest factor loadings and explains more of the variance than any other analysis; the analysis using ipsatised scores provides the worst results in supporting the Big Five structure.
