More models, more features: what’s new in ‘parameters’ 0.2.0

Improved Documentation

• Parameters Description

  • Guide to parameters description

• Parameters Engineering

  • Guide to bootstrapped parameters
  • Guide to standardized parameters

• Parameters Selection

  • Guide to parameters selection

• Dimension Reduction

  • Guide to feature reduction (PCA, cMDS, ICA…)
  • Guide to structural models (EFA, CFA, SEM…)

Improved Support

Besides stabilizing and improving the functions for the most popular models (glm(), glmer(), stan_glm(), psych and lavaan…), the functions p_value(), ci(), standard_error(), standardize() and most importantly model_parameters() now support many more model objects, including mixed models from packages nlme, glmmTMB or GLMMadaptive, zero-inflated models from package pscl, other regression types from packages gam or mgcv, fixed effects regression models from panelr, lfe, feisr or plm, and structural models from FactoMineR.

Improved Printing

For models with special components, in particular zero-inflated models, model_parameters() separates these components for a clearer output.
