Lavaan estimators
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. WebThe corresponding lavaan syntax for specifying this model is as follows: visual =~ x1 + x2 + x3 textual =~ x4 + x5 + x6 speed =~ x7 + x8 + x9 In this example, the model syntax only contains three ‘latent variable definitions’. Each formula has the following format: latent variable =~ indicator1 + indicator2 + indicator3
