- Fixed issues with
*glmmTMB*models with dispersion-parameter. - Fixed issue where
`model_parameters()`

for*glmmTMB*models falsely removed the`Component`

column. - Fixed issue with missing CI columns in
`model_parameters()`

when`standardize`

was one of the options except`"refit"`

. `parameters_type()`

did not correctly detect interaction terms for specific patterns like`scale()`

included in the interaction.

- Added vignette on model parameters and missing data.
- Update citation.

- Support for
`mipo`

(*mice*),`lqm`

and`lqmm`

(*lqmm*). Preliminary support for`semLME`

(*smicd*),`mle2`

(*bbmle*),`mle`

(*stats4*) `model_parameters()`

for objects of class`mira`

(*mice*).

`model_parameters()`

gets a specific behaviour for brms-meta-analysis models.`model_parameters()`

for*lavaan*and*blavaan*now also prints self-defined parameters.`model_parameters()`

for*lavaan*and*blavaan*gains more option for standardized parameters.

- Fix issue in
`model_parameters()`

for`coxph.penal`

models. - Fix issue in
`model_parameters.metaplus()`

with random effects. - Fix issue in
`check_heterogeneity()`

when`x`

was a mixed model. - Fix issue in
`check_heterogeneity()`

for data with missing values. - Fix issue in
`dof_ml1()`

when random-effect terms where character vectors. - Fix issue in
`print()`

method for`model_parameters()`

that printed empty lines for rows with complete missing values. Empty lines are now removed. - Fix issue in

`metaplus`

(*metaplus*),`glht`

(*multcomp*),`glmm`

(*glmm*),`manova`

(*stats*),`crq`

and`crqs`

(*quantreg*)- Improved support for models from the
*rms*package.

- Improved parameters formatting for ordered factors in
`model_parameters()`

(and`format_parameters()`

). - Argument
`df_method`

can now also be applied to GLMs, to allow calculation of confidence intervals based on Wald-approximation, not profiled confidence intervals. This speeds up computation of CIs for models fit to large data sets. - Improved
`select_parameters()`

for mixed models, and revised docs and associated vignette.

- Allow
`threshold`

to be passed to`efa_to_cfa()`

when the model is from`factor_analysis()`

. - Allow correlation matrix to be passed to
`factor_analysis()`

. - Fix CRAN check issues.

`simulate_parameters()`

and `simulate_model()`

- has a nicer
`print()`

method. - now also simulate parameters from the dispersion model for
*glmmTMB*objects. - gets a
`verbose`

argument, to show or hide warnings and messages.

- fix issue with rank deficient models.

- We changed the computation of confidence intervals or standard errors, so these are now based on a t-distribution with degrees of freedom and not normal distribution assuming infinite degrees of freedom. This was implemented for most functions before and only affects few functions (like
`equivalence_test()`

or CIs for standardized parameters from`model_parameters()`

when standardization method was`"posthoc"`

).

`averaging`

(*MuMIn*),`bayesx`

(*R2BayesX*),`afex_aov`

(*afex*)

`check_heterogeneity()`

as a small helper to find variables that have a within- and between-effect related to a grouping variable (and thus, may result in heterogeneity bias, see this vignette).

`equivalence_test()`

- gains a
`rule`

argument, so equivalence testing can be based on different approaches. - for mixed models gains an
`effect`

argument, to perform equivalence testing on random effects. - gains a
`p_values`

argument, to calculate p-values for the equivalence test. - now supports more frequentist model objects.

`describe_distribution()`

- now works on grouped data frames.

`ci`

and`iterations`

argument to show or hide parameters for group levels of random effects.- Improved accuracy of confidence intervals in
`model_parameters()`

with`standardize = "basic"`

or`standardize = "posthoc"`

. `model_parameters.merMod()`

no longer passes`...`

down to bootstrap-functions (i.e. when`bootstrap = TRUE`

), as this might conflict with`lme4::bootMer()`

.- For ordinal models (like
`MASS::polr()`

or`ordinal::clm()`

), a`Component`

column is added, indicating intercept categories (`"alpha"`

) and estimates (`"beta"`

). - The
`select`

-argument from`print.parameters_model()`

now gets a`"minimal"`

-option as shortcut to print coefficients, confidence intervals and p-values only.

`parameters_table()`

and`print.parameters_model()`

now explicitly get arguments to define the digits for decimal places used in output.`ci()`

for`anova()`

from mixed models can now also compute effect sizes like eta squared.`model_parameters()`

for`aov()`

gains a`type`

-argument to compute type-1, type-2 or type-3 sums of squares.`model_parameters()`

for Bayesian models gains a`standardize`

argument, to return standardized parameters from the posterior distribution.- Improved
`print()`

method for`model_parameters()`

for nested`aov()`

(repeated measurements). - You can now control whether
`demean()`

should add attributes to indicate within- and between-effects. This is only relevant for the`print()`

-method of`model_parameters()`

.

- Fixed
`model_parameters()`

for`anova()`

from*lmerTest*models.

`cluster_analysis()`

when`method = "kmeans"`

and`force = TRUE`

(factors now also work for kmeans-clustering).

`p_value_kenward()`

,`se_kenward()`

etc. now give a warning when model was not fitted by REML.- Added
`ci()`

,`standard_error()`

and`p_value()`

`standard_error()`

for*brmsfit*and*stanreg*objects.

- Run certain tests only locally, to reduce duration of CRAN checks.

`skewness()`

now uses a different method to calculate the skewness by default. Different methods can be selected using the`type`

-argument.`kurtosis()`

-argument.

- Added support for

(*cglm*),`DirichletRegModel`

(*DirichletReg*)

- Added new vignettes on ‘Standardized Model Parameters’ and ‘Robust Estimation of Standard Errors’, and vignettes are now also published on CRAN.

. This should now work for more models than before. - Improved accuracy of
`ci.merMod()`

for`method = "satterthwaite"`

and`method = "kenward"`

. `select_parameters()`

for*stanreg*models, which was temporarily removed due to the CRAN removal of package**projpred**, is now re-implemented.

`dof_betwithin()`

to compute degrees of freedom based on a between-within approximation method (and related to that,`p_value_*()`

and`se_*()`

for this method were added as well).`random_parameters()`

that returns information about the random effects such as variances, R2 or ICC.`closest_component()`

as a small helper that returns the component index for each variable in a data frame that was used in`principal_components()`

.`get_scores()`
