Web2 Feb 2024 · When calculating the mediation model with an ordered categorical outcome variable, lavaan automatically uses the DWLS estimator (with DWLS = Diagonally Weighted Least Squares). I was wondering whether the indirect effects can actually be interpreted with this estimator. WebML estimator is not recommended. In the context of the categorical variable estimation, the ADF estimator is most often referred to these days as WLS. The modified approach that has developed is a multiple-step estimation involving polychoric correlations as input to create the asymptotic covariance matrix used for weighting in the WLS estimation.
