bayestestR 0.17.0.xxx

CRAN release: 2025-08-29

New functionality

• as.matrix() for bayesfactor_restricted(), to obtain a matrix of Bayes factors between all restricted models.

Changes

• as.matrix(<bf>) now returns class bayesfactor_matrix and has a simpler printing.

bayestestR 0.17.0

CRAN release: 2025-08-29

Changes

• rope() (and by extension p_rope()) gain a new complement argument such that rope(x, complement = TRUE) returns the ROPE posterior probability together with the posterior probabilities above/below the ROPE (the complementary probabilities).

• Added display() methods for bayestestR objects. The display() methods also get a new format option, format = "tt", to produce tables with the tinytable package.

• The long deprecated rnorm_perfect() function has been removed. Use distribution_normal() instead.

• Prepare for upcoming changes in marginaleffects (0.29.0).

bayestestR 0.16.1

CRAN release: 2025-07-01

Changes

• Improved efficiency for describe_posterior().

• Minor improvements for models with multinomial response variables.

• Minor improvements for mixture models from package brms.

bayestestR 0.16.0

CRAN release: 2025-05-20

Changes

• Revised code-base to address changes in latest insight update. Dealing with larger models (many parameters, many posterior samples) from packages brms and rstanarm is more efficient now. Furthermore, the options for the effects argument have a new behavior. "all" only returns fixed effects and random effects variance components, but no longer the group level estimates. Use effects = "full" to return all parameters. This change is mainly to be more flexible and gain more efficiency for models with many parameters and / or many posterior draws.

bayestestR 0.15.3

CRAN release: 2025-04-28

Changes

• effective_sample(), and functions that call effective_sample() (like describe_posterior() with the respective test option) now also return the tail ESS.

Bug fixes

• describe_posterior() now returns a columns with response levels for marginaleffects objects applied to categorical or multinomial Stan models.

• describe_posterior() now returns a columns with response variables for marginaleffects objects applied to multivariate response Stan models.

• Fixed issue in map_estimate() and point_estimate(centrality = "MAP") for vectors with only one unique value.

bayestestR 0.15.2

CRAN release: 2025-02-07

Changes

• describe_posterior() no longer re-samples a model when computing indices.

• describe_posterior() calls tests only when needed. Before, there was a minimal overhead by calling tests that were not requested.

Bug fixes

• Fixed failing test for Mac OS.

bayestestR 0.15.1

CRAN release: 2025-01-17

Changes

• Several minor changes to deal with recent changes in other packages.

Bug fixes

• Fix to emmeans / marginaleffects / data.frame(<rvar>) methods when using multiple credible levels (#688).

bayestestR 0.15.0

CRAN release: 2024-10-17

Changes

• Support for posterior::rvar-type column in data frames. For example, a data frame df with an rvar column ".pred" can now be called directly via p_direction(df, rvar_col = ".pred").

• Added support for marginaleffects

• The ROPE or threshold ranges in rope(), describe_posterior(), p_significance() and equivalence_test() can now be specified as a list. This allows for different ranges for different parameters.

• Results from objects generated by emmeans (emmGrid/emm_list) now return results with appended grid-data.

• Usability improvements for p_direction():

  • Results from p_direction() can directly be used in pd_to_p().

  • p_direction() gets an as_p argument, to directly convert pd-values into frequentist p-values.

  • p_direction() gets a remove_na argument, which defaults to TRUE, to remove NA values from the input before calculating the pd-values.

  • Besides the existing as.numeric() method, p_direction() now also has an as.vector() method.

• p_significance() now accepts non-symmetric ranges for the threshold argument.

• p_to_pd() now also works with data frames returned by p_direction(). If a data frame contains a pd, p_direction or PD column name, this is assumed to be the pd-values, which are then converted to p-values.

• p_to_pd() for data frame inputs gets a as.numeric() and as.vector() method.

Bug fixes

• Fixed warning in CRAN check results.

bayestestR 0.14.0

CRAN release: 2024-07-24

Breaking Changes

• 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 bayestestR: estimate_density().

Changes

• bayesian_as_frequentist() now supports more model families from Bayesian models that can be successfully converted to their frequentists counterparts.

• bayesfactor_models() now throws an informative error when Bayes factors for comparisons could not be calculated.

Bug fixes

• Fixed issue in bayesian_as_frequentist() for brms models with 0 + Intercept specification in the model formula.

bayestestR 0.13.2

CRAN release: 2024-02-12

Breaking Changes

• 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.

Changes

• Retrieving models from the environment was improved.

Bug fixes

• 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.

Bug fixes

• 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.

bayestestR 0.13.0

CRAN release: 2022-09-18

Breaking

• contr.equalprior(contrasts = FALSE) (previously contr.orthonorm) no longer returns an identity matrix, but a shifted diag(n) - 1/n, for consistency.

New functionality

• 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.

• p_direction() now accepts objects of class parameters_model() (from parameters::model_parameters()), to compute probability of direction for parameters of frequentist models.

bayestestR 0.12.1

CRAN release: 2022-05-02

Breaking

• 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 ns.

New functions

• 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".

Changes

bayestestR 0.9.0

CRAN release: 2021-04-08
