- Better handling of
`AsIs`

-variables with division-operation as dependent variables, e.g. if outcome was defined as`I(income/frequency)`

, especially for`find_response()`

and`get_data()`

. - Revised package-functions related to
`felm`

-models due to breaking changes in the*lfe*-package.

`iv_robust`

(*estimatr*),`crch`

(*crch*),`gamlss`

(*gamlss*),`lmrob`

and`glmrob`

(*robustbase*, #64),`rq`

,`rqss`

and`crq`

(*quantreg*),`rlmer`

(*robustlmm*),`mixed`

(*afex*),`tobit`

(*AER*) and`survreg`

(*survival*).

`get_variance()`

, to calculate the variance components from mixed models of class`merMod`

,`glmmTMB`

,`MixMod`

,`rlmer`

,`mixed`

,`lme`

and`stanreg`

(#52). Furthermore, convenient shortcuts to return the related components directly, like`get_variance_random()`

or`get_variance_residual()`

.`find_algorithm()`

, to get information about sampling algorithms and optimizers, and for Bayesian models also about chains and iterations (#38).`find_random_slopes()`

, which returns the names of the random slopes of mixed models.`get_priors()`

, to get a summary of priors used for a model (#39).`is_model()`

to check whether an object is a (supported) regression model (#69).`all_models_equal()`

to check whether objects are all (supported) regression models and of same class.`print_color()`

(resp.`print_colour()`

) to print coloured output to the console. Mainly implemented to reduce package dependencies.

`find_parameters()`

and`get_parameters()`

get a`parameters`

-argument for`brmsfit`

and`stanreg`

models, to allow selection of specific parameters that should be returned (#55).`find_parameters()`

and`get_parameters()`

now also return simplex parameters of monotic effects (**brms**only) and smooth terms (e.g. for gam-models).`find_terms()`

and`find_predictors()`

no longer return constants, in particular`pi`

(#26).- For
`gls`

and`lme`

objects, functions like`find_formula()`

etc. also return the correlation component (#19). `model_info`

now returns`$is_tweedie`

for models from tweedie-families.

`find_parameters()`

and`get_parameters()`

did not preserve coefficients of monotonic category-specific effects from**brmsfit**-objects.- Fixed bug that sometimes returned more elements for
`find_predictors()`

or`get_parameters()`

than requested. - Fixed bug in
`get_data()`

for**MixMod**-objects when response variable was defined via`cbind()`

. - Fixed bug in
`get_response()`

for models that used`cbind()`

with a substraction (e.g.`cbind(success, total - success)`

). In such cases, values for second column (in this example:`total`

) were the substracted values`total - success`

, not the original values from`total`

.

- Initial release.
