parameters 0.29.2

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.
