WebDetails. The population covariance matrix is estimated by svyvar and passed to factanal. Although fitting these models requires only the estimated covariance matrix, inference requires a sample size. With n="sample", the sample size is taken to be the number of observations; with n="degf", the survey degrees of freedom as returned by degf. WebAmong the many ways to do latent variable exploratory factor analysis (EFA), one of the better is to use Ordinary Least Squares (OLS) to find the minimum residual (minres) solution. This produces solutions very similar to maximum likelihood even for badly behaved matrices. A variation on minres is to do weighted least squares (WLS).
