`pd_to_p()`

now returns 1 and a warning for values smaller than 0.5.`map_estimate()`

,`p_direction()`

,`p_map()`

, and`p_significance()`

now return a data-frame when the input is a numeric vector. (making the output consistently a data frame for all inputs.)Argument

`posteriors`

was renamed into`posterior`

. Before, there were a mix of both spellings, now it is consistently`posterior`

.

- Retrieving models from the environment was improved.

Fixed issues in various

`format()`

methods, which did not work properly for some few functions (like`p_direction()`

).Fixed issue in

`estimate_density()`

for double vectors that also had other class attributes.Fixed several minor issues and tests.

Improved speed performance when functions are called using

`do.call()`

.Improved speed performance to

`bayesfactor_models()`

for`brmsfit`

objects that already included a`marglik`

element in the model object.

`as.logical()`

for`bayesfactor_restricted()`

results, extracts the boolean vector(s) the mark which draws are part of the order restriction.

`p_map()`

gains a new`null`

argument to specify any non-0 nulls.Fixed non-working examples for

`ci(method = "SI")`

.Fixed wrong calculation of rope range for model objects in

`describe_posterior()`

.Some smaller bug fixes.

The minimum needed R version has been bumped to

`3.6`

.`contr.equalprior(contrasts = FALSE)`

(previously`contr.orthonorm`

) no longer returns an identity matrix, but a shifted`diag(n) - 1/n`

, for consistency.

`p_to_bf()`

, to convert p-values into Bayes factors. For more accurate approximate Bayes factors, use`bic_to_bf()`

.*bayestestR*now supports objects of class`rvar`

from package*posterior*.`contr.equalprior`

(previously`contr.orthonorm`

) gains two new functions:`contr.equalprior_pairs`

and`contr.equalprior_deviations`

to aide in setting more intuitive priors.

- has been renamed
to be more explicit about its function.`contr.equalprior`

`p_direction()`

now accepts objects of class`parameters_model()`

(from`parameters::model_parameters()`

), to compute probability of direction for parameters of frequentist models.

`Bayesfactor_models()`

for frequentist models now relies on the updated`insight::get_loglikelihood()`

. This might change some results for REML based models. See documentation.`estimate_density()`

argument`group_by`

is renamed`at`

.All

`distribution_*(random = FALSE)`

functions now rely on`ppoints()`

, which will result in slightly different results, especially with small`n`

s.Uncertainty estimation now defaults to

`"eti"`

(formerly was`"hdi"`

).

*bayestestR*functions now support`draws`

objects from package*posterior*.`rope_range()`

now handles log(normal)-families and models with log-transformed outcomes.New function

`spi()`

, to compute shortest probability intervals. Furthermore, the`"spi"`

option was added as new method to compute uncertainty intervals.

`bci()`

for some objects incorrectly returned the equal-tailed intervals.

- Fixes failing tests in CRAN checks.

`describe_posterior()`

gains a`plot()`

method, which is a short cut for`plot(estimate_density(describe_posterior()))`

.

Fixed issues related to last

*brms*update.Fixed bug in

`describe_posterior.BFBayesFactor()`

where Bayes factors were missing from out put ( #442 ).

- All Bayes factors are now returned as
`log(BF)`

(column name`log_BF`

). Printing is unaffected. To retrieve the raw BFs, you can run`exp(result$log_BF)`

.

`bci()`

(and its alias`bcai()`

) to compute bias-corrected and accelerated bootstrap intervals. Along with this new function,`ci()`

and`describe_posterior()`

gain a new`ci_method`

type,`"bci"`

.

`contr.bayes`

has been renamedto be more explicit about its function.`contr.orthonorm`

The default

`ci`

width has been changed to 0.95 instead of 0.89 (see here). This should not come as a surprise to the long-time users of`bayestestR`

as we have been warning about this impending change for a while now :)Column names for

`bayesfactor_restricted()`

are now`p_prior`

and`p_posterior`

(was`Prior_prob`

and`Posterior_prob`

), to be consistent with`bayesfactor_inclusion()`

output.Removed the experimental function

`mhdior`

.

Support for

`blavaan`

models.Support for

`blrm`

models (*rmsb*).Support for

method for the`mediation()`

function.Fixed remaining inconsistencies with CI values, which were not reported as fraction for

`rope()`

.Fixed issues with special prior definitions in

`check_prior()`

,`describe_prior()`

and`simulate_prior()`

.

Support for

`bamlss`

models.Roll-back R dependency to R >= 3.4.

no longer errors for no reason when computing extremely un/likely direction hypotheses.`bayesfactor_pointull()`

/`bf_pointull()`

are now`bayesfactor_pointnull()`

/`bf_pointnull()`

(can*you*spot the difference? #363 ).

, a function for sequential effect existence and significance testing (SEXIT).

Added startup-message to warn users that default ci-width might change in a future update.

Added support for

*mcmc.list*objects.

`unupdate()`

gains a`newdata`

argument to work with`brmsfit_multiple`

models.Fixed issue in Bayes factor vignette (don’t evaluate code chunks if packages not available).

Added

`as.matrix()`

function for`bayesfactor_model`

arrays.`unupdate()`

, a utility function to get Bayesian models un-fitted from the data, representing the priors only.

- both Bayesian and frequentist ( #312 - cross fix with`parameters`

)

Fixed issue with

*default*rope range for`BayesFactor`

models.Fixed issue in collinearity-check for

`rope()`

for models with less than two parameters.Fixed issue in print-method for

`mediation()`

with`stanmvreg`

-models, which displays the wrong name for the response-value.Fixed issue in

for models with only one parameter.`rope_range()`

for`BayesFactor`

models returns non-`NA`

values ( #343 )
