You must submit your correlations or covariances into a com-. puter program to extract your factors. This step is too complex to reasonably be done by hand. There. are a number of diï¬erent extraction methods, including maximum likelihood, principal component, and principal axis extraction. The best method is generally maximum likelihood extraction, unless you. seriously lack multivariate normality in your measures.
