WebJul 15, 2015 · The diagonal weight matrix W D = diag(Ṽ) is more flexible (i.e., need not be positive-definite) than the full weight matrix W = Ṽ (Kaplan, 2009; Kline, 2011; Muthén et al., 1997). The diagonal weight matrix prevents software programs from engaging in extensive computations and encountering numerical problems in model estimation. WebIt seems that the major difference between the fa function and Mplus is that the latter uses a robust weighted least squares factoring method (WLSMV - a diagonal weight matrix), whereas the former uses a regular weighted least squares (WLS) factoring method.
