Description

Breaking Changes

  • The standardize argument in factor_analysis() now defaults to FALSE.

  • The rotation argument in factor_analysis() now defaults to "oblimin", because the former default of "none" rarely makes sense in the context of factor analysis. If you want to use no rotation, please set rotation = "none".

  • The cor argument in n_factors() was renamed into correlation_matrix. In factor_analysis(), the cor argument was completely removed to avoid naming collision with the cor argument of psych::fa(), which now users can pass the cor argument to psych::fa() when using factor_analysis().

Changes

  • factor_analysis() gets a .matrix method, including arguments n_obs and n_matrix, to compute factor analysis for a correlation matrix or covariance matrix.

  • New function factor_scores() to extract factor scores from EFA (psych::fa() or factor_analysis()).

  • Added and/or improved print-methods for all functions around PCA, FA and Omega.

  • Improved efficiency in model_parameters() for models from packages brms and rstanarm.

  • p_adjust for model_parameters() gets a new options, "sup-t", to calculate simultaneous confidence intervals.

Bug fixes

  • bootstrap_model() did not work for intercept-only models. This has been fixed.

  • Fixed issue with printing labels as pretty names for models from package pscl, i.e. print(model_parameters(model), pretty_names = "labels") now works as expected.
