Changes simulate_model(), simulate_parameters() and equivalence_test() now work for lavaan objects. Added format() method for objects returned by factor_analysis() and principal_components(). Bug fixes Fixed issues with extracting wrong standard errors for model with frailty terms in survival::coxph(). Fixed issue where including a character variable in a model caused all other variable labels to be silently dropped from model_parameters() output (#1142). Fixed issue where on-the-fly factor conversions in the model formula (e.g., factor(cyl)) produced NA in interaction labels when variable labels were set (#1135). Fixed issue where include_reference = TRUE had no effect for pscl::zeroinfl() and pscl::hurdle() models (#1130). Fixed issue with calculation of standard errors in model_parameters() when vcov was a function that errored when unsupported arguments were passed. Fixed issue in print_html() for model_parameters() with lavaan objects.
