"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.
