insight 0.20.2

New supported models

• Support for models of class glmgee (package glmtoolbox).

• Support for models of class svy2lme (package svylme).

General

• Massive overhaul of get_variance(). The function should be now more accurate for different distributional families, in particular for mixed regression models with Beta family.

• Improved accuracy of singularity-checks in get_variance().

• get_variance() gets a few new arguments:

  • null_model, to provide a null-model to be used for the calculation of random effect variances. If NULL, the null-model is computed internally. This argument is optional, but may be useful to save time, or when the null-model cannot be calculated internally.

  • approximation, indicating the approximation method for the distribution-specific (observation level, or residual) variance.

  • model_component, for models that can have a zero-inflation component, specify for which component variances should be returned. By default, both the conditional and the zero-inflation component are taken into account.

• Fix CRAN check issues due to the last fixest update.

Changes to functions

Bug fixes

• Fixed issue with invalid multibyte strings in trim_ws().

• Fixed issue in find_statistic() for models from package fixest.

• get_data() for lavaan models is now more stable at retrieving model data when this is not available in the environment.

insight 0.19.0

New supported models

• mmrm (package mmrm), flac and flic (logistf)

Breaking changes

• get_data() was revised and now always tries to recover the data that was used to fit a model from the environment. If this fails, it falls back to recovering data from the model frame (the former default behaviour). Furthermore, the source argument can be used to explicitly force the old behaviour: source = "mf" will try to recover data from the model frame first, then possibly falling back to look in the environment.

New functions

• n_grouplevels(), to return random effect groups and number of group levels for mixed models.

Changes to functions

• get_datagrid() preserves all factor levels for factors that are hold constant at their reference level. This is required to work together with get_modelmatrix() when calculating standard errors for get_predicted().

• Fixed minor issues for HTML tables in export_table() when model parameters were grouped.

• Fixes issue in compact_list().

New functions

• safe_deparse_symbol() to only deparses a substituted expressions when possible,which increases performance in case many calls to deparse(substitute()).

Changes to functions

• format_table() gets a use_symbols argument. If TRUE, column names that refer to particular effectsizes (like Phi, Omega or Epsilon) include the related unicode-character instead of the written name. This only works on Windows for R >= 4.2, and on OS X or Linux for R >= 4.0.

• The stars argument in format_table() can now also be a character vector, naming the columns that should include stars for significant values. This is especially useful for Bayesian models, where we might have multiple columns with significant values, e.g. "BF" for the Bayes factor or "pd" for the probability of direction.

• get_df() gets more type options to return different type of degrees of freedom (namely, "wald" and "normal", and for mixed models, "ml1", "betwithin", "satterthwaite" and "kenward-roger").

• standardize_names() now recognized more classes from package marginaleffects.

• Minor improvements to find_parameters() for models with nonlinear formula.

• Minor speed improvements.

Bug fixes

• Fixed issue in get_data() for models of class plm, which accidentally converted factors into character vectors.

• Fixed issue with column alignment in export_table() when the data frame to print contained unicode-characters longer than 1 byte.

• format_table() now merges IC and IC weights columns into one column (e.g., former columns "AIC" and "AIC_wt" will now be printed as one column, named "AIC (weights)"). Furthermore, an ic_digits argument was added to control the number of significant digits for the IC values.

• print_color() and color_text() now support bright variants of colors and background colors.

• get_datagrid() gets more options for at and range, to provide more control how to generate the reference grid.

• is_converged(), to check whether a mixed model has converged or not.

Changes to functions

• get_predicted() gets a method for models of class gamlss (and thereby, get_loglikelihood() now also works for those model classes).

• get_predicted() now better handles models of class polr, multinom and rlm.

Bug fixes

• Fixed test failures.

• Minor fixes to address changes in other packages.

insight 0.18.0

Breaking changes

• The ci argument in get_predicted() now defaults to NULL. One reason was to make the function faster if confidence intervals are not required, which was the case for many downstream usages of that function. Please set ci explicitly to compute confidence intervals for predictions.

• get_data() no longer returns logical types for numeric variables that have been converted to logicals on-the-fly within formulas (like y ~ as.logical(x)). Instead, for each numeric variable that was coerced to logical within a formula gets a logical attribute (set to TRUE), and the returned data frame gets a logicals attribute including all names of affected variables.

• parameters_table(), the alias for format_table(), was removed.

Changes to functions

• find_transformation() and get_transformation() now also work for models where the response was transformed using log2() or log10().

• clean_names() now works correctly when several variables are specified in s() (#573, @etiennebacher).

insight 0.17.1

New supported model classes

• deltaMethod (car), marginaleffects, marginaleffects.summary (marginaleffects)

General

• get_predicted() now supports models of class iv_robust and ivreg.

• For get_predicted(), when both type and predict are given, type will overwrite predict. Note that this will print a message, because predict is the preferred argument.

• get_varcov() gains vcov and vcov_args arguments, to specify the variance-covariance matrix used to compute uncertainty estimates (e.g., for robust standard errors).

• get_loglikehood() improved handling of models from package estimator.

Bug fixes

• Fixed bug in get_data() for model objects whose data needs to be recovered from the environment, and where the data name was a reserved word (e.g., named like an R function).

• get_data.coxph() returns the original data frame instead of data with type coercion.

• get_loglikelihood() gets a check_response argument, to check if a model has a transformed response variable (like log() or sqrt() transformation), and if so, returns a corrected log-likelihood.

• get_predicted() was improved for multinomial models from brms.

• get_variance() was improved to cover more edge cases of (more complex) random effect structures.

• In some edge cases, where get_data() is unable to retrieve the data that was used to fit the model, now a more informative error is printed.

• ellipses_info() now also accepts a list of model objects, is more stable and returns more information about the provided models (like if all fixed or random effects are the same across models, if all models are mixed models or null-models, etc.)

• check_if_installed() now works interactively and lets the user prompt whether to automatically update or install packages.

Bug fixes

• Fixed incorrect column name conversion in standardize_names() for certain columns returned by broom::glance().
