insight 1.0.0

Breaking changes

• All deprecated arguments have been removed.

• The table_width argument in export_table() now defaults to "auto".

General

• get_transformation() can now deal with any power-transformation, and also
  returns results for divisions (scaled response) and Box-Cox transformations.

• find_transformation() and get_transformation() now also detects use of
  divisions, like x/3 or Box-Cox transformations (like (x^lambda - 1) / lambda).

• find_transformation() and get_transformation() get a include_all argument,
  to check all model terms for transformations.

• get_dispersion() is now an exported function.

• Updated get_varcov() (and related documentation) to support new covariance
  matrix estimation methods from the sandwich package.

• New function validate_argument() as a replacement for match.arg() with
  more informative error message.

• The function to calculate the corrections for likelihood-values when the
  response-variable is transformed is now exported as get_likelihood_adjustment().

• export_table() can now split tables into more than three tables when
  table_width is used (formerly, the maximum number of split tables was three).

• Changed (improved) formatting for parameter tables in export_table(), when
  format = "html". Rows are indented, and group headers are emphasized in
  italic.

• formula_ok() now also checks for syntactically invalid variable names.
  Furthermore, argument checks now allows to specify for which possibly
  problematic formula notation should be checked.

• format_value() gains a decimal_point argument, to change the decimal point
  in output conversion.

• format_bf() with stars = TRUE uses the ° symbol for inferiority
  (evidence against the comparison).

• Added support for coxph.panel models.

• Added support for models of class asym (package panelr).

• Overhaul of documentation for the package-functions.

Bug fix

• clean_parameters() now uses the correct labels for the random effects
  variances ("SD/Cor" has changed to "Var/Cov").

• When get_data() could not properly evaluate the subset of a data set, it
  now returns an informative warning and no longer errors.

• Fixed inaccuracy in get_sigma() for models of class brmsfit.

• Fixed issues in get_variance() for models of class brmsfit when the
  sigma-parameter was directly modeled.

• Fixed issue in compact_character() and compact_list() for date-variables.

• Fixed edge case in find_transformation() for simple log-transformation of
  the response variable.

• Fixed issue for model_info.averaging().

insight 0.20.5

General

• get_datagrid() can now be used to extract the "grid" information from
  {emmeans} and {marginaleffects} outputs.

• Arguments na.rm and na_rm are deprecated throughout the package's functions.
  Instead, use remove_na.

Bug fixes

• Fixed rendering issue of the example in ?insight::display.

• Fixed issues due to recent changes in the glmmTMB package.

insight 0.20.4

New supported models

• Support for models of classes glm_weighit, multinom_weightit and
  ordinal_weightit (package WeightIt).

Changes

• null_model() and formula_ok() now warn when indexed data frames, such as
  df[, 5], are used as response variable in the formula, as this can lead to
  unexpected results.

• Minor improvements to link_function() and link_inverse().

Bug fixes

• Fixed regression from latest fix related to get_variance() for brms models.

• Fixed issue in link_function() and link_inverse() for models of class
  cglm with "identity" link, which was not correctly recognized due to a
  typo.

insight 0.20.3

Changes

• get_df() now supports more model classes.

• get_variance() gives an informative error if no mixed model is provided.

Bug fixes

• Fixed issue in find_formula(), find_predictors() and find_variables()
  for models from package brms with custom formulas.

• Fixed issues in find_response() for brms models with mi() function in
  the response variable.

• Fixed issue in get_variance() that could lead to recursive calls for
  brms models, resulting in "infinite" resampling of the model.

• Fixed issue in check_if_installed() that erroneously tried to guess the
  minimum required package version based on the SUGGEST field of the insight
  package, instead of the package that was calling the function.

• Fixed issue in get_modelmatrix() for models from package brms with
  special functions in the formula (like mo()).

• Fixed issue in ellipses_info() when this function was called from do.call().

• Fixed issue with formatting unicode-symbols, where a wrong unicode-character
  was used for "Omega". Furthermore, Omega2 and Eta2 are now correctly converted.

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.

• format_alert() and format_warning() get an immediate argument, to output
  warnings immediately.

• find_terms() and find_transformation() now better cope with inverse
  transformations of the response value, such as 1/y.

• get_transformation() now returns more transformations for power-transformed
  response variables.

• model_info() for MixMod objects from package GLMMadaptive now recognize
  zero-inflation and hurdle models for custom families.

Bug fixes

• null_model() now correctly handles zero-inflated models from package
  glmmTMB.

• Fixed issue in null_model() for models from package GLMMadaptive.

• Fixed issues in link_inverse() and link_function() for models of class
  gamlss from LOGNO() family.

insight 0.20.1

Bug fixes

• Fixed possible memory allocation issues when the deprecated argument at was
  used in get_datagrid()

insight 0.20.0

Breaking

• Arguments named group, at, group_by and split_by will be deprecated
  in future releases of easystats packages. Please use by instead. This
  affects following functions in insight:

  • export_table()
  • get_datagrid()
  • print_parameters()

Bug fixes

• Fixed errors in CRAN checks.

• Fixed issues in compact_list() for objects that contained variables of
  class vctrs.

insight 0.19.11

General

• More informative error message for get_varcov() when the requested
  vcov-function failed.

Bug fixes

• Fixed issue with get_data() for coxme models when sourcewas set to
  "modelframe".

insight 0.19.10

Bug fixes

• Functions like find_variables() or clean_names() now support multi-membership
  formulas for models from brms.

• Updated tests to work with the latest changes in glmmTMB 1.1.9.

insight 0.19.9

New supported models

• Support for models of class serp (package serp).

General

• standardize_names() now also recognizes column s.value from objects of
  package marginaleffects.

Bug fixes

• Fixed issue in find_predictors() for models with splines (s()), where
  number of dimensions was indicated with a variable, not a number.

• format_ci() now works for factors and character vectors again.

• Fixed issues with latest release of tinytable.

• Fixed issues with latest release of PROreg.
