- The function to calculate null-models for mixed effects models is now exported (
`null_model()`

.)

`arima`

(*stats*),`averaging`

(*MuMIn*)

- Improve family detection in
`model_info()`

,`link_inverse()`

and`link_function()`

for*MCMCglmm*. - Minor revisions to meet changes in
*mlogit*package. - Improve support for
*bayesx*and*BBmm*models.

- Fixed issue in
`find_parameters()`

and`clean_parameters()`

for*brmsfit*models with specific variable name patterns. - Fixed issue in
`format_ci()`

when confidence interval only contained`NA`

s and`width`

was set to`"auto"`

. - Fixed issue in
`find_formula()`

for mixed models when formula contained parentheses in the non-random parts, around a certain set of predictors. - Fixed issue in
`get_priors.BFBayesFactor()`

for`BFMetat`

class. - Fixed issue in
`clean_parameters.BFBayesFactor()`

when model contained interaction terms and these were assigned to the “extra” component.

`model_info()`

now only returns`TRUE`

for`$is_ordinal`

, when model is an ordinal or cumulative link model. In past versions,`$is_ordinal`

was also`TRUE`

for multinomial models.

`bife`

(*bife*),`bcplm`

and`zcpglm`

(*cplm*)

- Improved support for
`clogit`

-models.

- Fixed issue in

for mixed models with complex offset-terms. - Fixed issue in
`get_statistic()`

for*zeroinfl*models with theta-coefficients. - Fixed issue in
`get_statistic()`

`find_parameters()`

for*brmsfit*models for rare situations where a specific pattern of variables names, when used as random effects, did not properly separate fixed from random effects in the return value. - Fixed issue related to CRAN checks.

`cglm`

(*cglm*),`DirichletRegModel`

(*DirichletReg*).

- Improved efficiency of
`find_parameters()`

and`get_parameters()`

for mixed models with large samples and many random effects, and only fixed effects where requested.

`model_info()`

now returns`$is_multinomial`

for multinomial (but not ordinal or cumulative) link models.`format_value()`

gets an`as_percent`

argument to format values as percentages.

- Fixed issue in
`get_data()`

for*clmm2*-models. - Fixed issue in
`get_data()`

(*MANOVA.RM*).

- Better handling of
`clm2`

,`clmm2`

and`rqss`

models.

`format_ci()`

(re-implemented and slightly enhanced from*parameters*), to format confidence/credible intervals.

`find_parameters()`

now also works for`BFBayesFactor`

objects.- Suppress non-informative warning in
`get_data()`

for model data with weights. `format_value()`

automatically uses scientific notation for*very*large numbers (> 1e+5). Furthermore, the check for integer values was made more robust, to avoid warnings when checking*very*large numbers for integer type.- Improved
`find_parameters()`

,`get_parameters()`

and`clean_parameters()`

for`BFBayesFactor`

-objects. `get_priors()`

now works for`stanmvreg`

objects.- Other minor improvements.

- Better detect Tweedie-models in
`model_info()`

. - Fixed issue in
`find_random_slopes()`

for*panelr*-models with multiple random-effect parts. - Fixed issues with
`zerotrunc`

models. - Fixed issues with
`brmsfit`

models with correlated random effects. - Fixed issue with edge-cases in
`clean_names()`

. - Fixed issue with breaking changes with latest
*brms*-update. - Further minor bug fixes.

`complmrob`

(*complmrob*),`fixest`

(*fixest*),`mclogit`

and`mmclogit`

(*mclogit*).

- Fixed bug in
`find_formula()`

for mixed models, when random effects are written before any fixed effects terms (like`social ~ (1|school) + open + extro`

). - Fixed bug in
`model_info()`

for*VGAM*models, where logit-link was not always correctly identified. - Fixed issue in
`get_priors()`

for*brmsfit*models, where parameters of conditional and zero-inflated model components had identical names. This caused errors in`bayestestR::simulate_prior()`

. - Fixed CRAN check issue.

- In order to unify column names across easystats-packages,
`get_parameters()`

and`get_priors()`

now return column names according to our naming conventions (i.e. capitalized column names). `model_info()`

returned both`$is_zeroinf`

and`$is_zero_inflated`

for zero-inflated models. Now`$is_zeroinf`

is softly deprecated, so`model_info()`

will return`$is_zero_inflated`

only in future updates.

`aareg`

(*survival*),`brmultinom`

and`bracl`

(*brglm2*), and`wbgee`

(*panelr*). Furthermore, for different model-types from*panelr*models (within-between, between, etc.) are now also supported.- Preliminary support for
`rma`

models (*metafor*).

`get_statistic()`

supports`multinom`

models (*nnet*).`link_inverse()`

gets a`what`

-argument, to return the link-inverse function for specific distribution parameters from**gamls**models.

- Fixed edge case for
`find_weights()`

. - Fixed bug in
`get_statistic()`

for*glmmTMB*models that won’t return any data.

`bayesx`

(*R2BayesX*),`bamlss`

(*bamlss*) and`flexsurvreg`

(*flexsurv*). Note that support for these models is still somewhat experimental.- Support for
*lavaan*and*blavaan*was added, but only applies to some of the functions:`get_data()`

,`get_parameters()`

,`find_parameters()`

,`clean_parameters()`

,`find_algorithm()`

and`get_priors()`

(the two latter only for*blavaan*).

`get_statistic()`

to return the test statistic of model estimates.`get_varcov()`

to return the variance-covariance matrix for models.`supported_models()`

to print a list of supported models.

`model_info()`

now returns the element`is_survival`

for survival models.`model_info()`

now returns the element`is_truncated`

for truncated regression, or*brmsfit*models with`trunc()`

as additional response part.`model_info()`

now recognizes beta and beta inflated families from package*gamlss*.- Better support for nonlinear quantile regression (
`quantreg::nlrq()`

). - Better support for nonlinear mixed models (
`lme4::nlmer()`

). Note that model-specification requires the random term to be written in parentheses, i.e.`(slope | group)`

.

- Fixed issues in
`get_data()`

,`find_parameters()`

and`get_parameters()`

for*gamlss*models. - Fixed issue in
`get_data()`

for*plm*models, where the`index`

-argument was used in the`plm()`

-function call. - Fixed issue in
`get_data()`

,`find_predictors()`

and`find_variables()`

for*brmsfit*multi-membership-models. `is_model()`

did not recognize objects of class`anova`

and`manova`

.`model_info()`

now correctly recognizes censored regression models from*brmsfit*.- Fixed issues in
`find_parameters()`

and`get_parameters()`

with*multinom*models. - Fixed issues in
`clean_names()`

for cases where variable transformations where made in specific patterns, like`log(test/10)`

.

- The previous
`is_model()`

function has been renamed to`is_model_supported()`

since it was unclear if the function checked the entered object was a model or a supported model in*insight*. The new`is_model()`

function checks if the entered object is a model object, while`is_model_supported()`

checks if a supported model object.

`find_statistic()`

to return the test statistic of a regression model.`format_value()`

and`format_table()`

as utility-functions to format (model) output, especially for tabular output.`color_if()`

as utility-function to add color formatting to values, depending on certain conditions.

- Make extraction of model family information more stable for gam-objects.

`find_parameters()`

and`get_parameters()`

now also support objects of class`sim`

and`sim.merMod`

(from`arm::sim()`

).`get_variance()`

now also supports models of class*clmm*.`find_predictors()`

and`find_variables()`

now include the Euclidean distance matrix for spatial models from*glmmTMB*(returned as random effects element, or more precise, as random slope).

`find_formula()`

now extracts group factors of random effects for*gamlss*models.`find_parameters()`

and`get_parameters()`

no longer show`NA`

coefficients from group factors of random effects for*gamlss*models.`find_parameters()`

and`get_parameters()`

did not work for multivariate response models of class*brmsfit*when argument`parameters`

was specified.`get_data()`

dropped value and variable label attributes, when model frame contained matrix variables (like splines).`get_priors()`

swapped column names`location`

and`scale`

for*brmsfit*-objects.`get_parameters()`

did not work for*glmmTMB*models without zero-inflation component.`find_predictors()`

did not remove parentheses from terms in multiple nested random effects.- Better support for
*gam*models (package*mgcv*) with`ziplss`

or`mvn`

families.

`get_variance()`

now supports models with Gamma-family.`get_weights()`

and`find_weights()`

now work for*brms*-models.

- Fix CRAN-check issues due to recent update from the
*panelr*-package.
