BREAKING CHANGES
tr = 0.1 to tr = 0.2 (which is what WRS2 defaults to).MAJOR CHANGES
expr_template gains a new argument bayesian, which can return an expression for Bayesian analysis, which has a slightly different template. Additionally, it has changed its conventions about the column names it expects.
Retires the additional caption-making functionality that was unique to expr_meta_random when type = "parametric". This was the only context in which this feature was supported and was therefore inconsistent with the rest of the package API.
Removes tidy_model_performance function, which is no longer used internally.
Removes column containing log values of Bayes Factor as they are relevant only for expressions.
All meta-analysis packages move from Imports to Suggests to reduce the installation time for the user.
All robust tests in this package were based on trimmed means, except for correlation test. This has been changed: the robust correlation measure is now Winsorized correlation, which is based on trimming. Therefore, the beta argument has been replaced by tr argument. This should result only in minor changes in correlation coefficient estimates.
BREAKING CHANGES
To be consistent with ggstatsplot’s overall syntax philosophy the type argument can be used to specify which type of statistical approach is to be used for all functions.
expr_t_parametric, expr_t_nonparametric, expr_t_robust, expr_t_bayes are now removed in favor of a single function expr_t_twosample.
expr_anova_parametric, expr_anova_nonparametric, expr_anova_robust, expr_anova_bayes are now removed in favor of a single function expr_oneway_anova.
statsExpressions no longer internally relies on tidyBF. All Bayesian analysis is carried out in this package itself. This was done to make the maintenance of this package easier and helps with some major internal code refactoring. As such, all re-exported functions from tidyBF have also been removed.
BUG FIXES
expr_contingency_tab ignored ratio argument while computing Cramer’s V for one-sample test. This is fixed.MAJOR CHANGES
All non-parametric functions now use effectsize package to compute effect sizes and not rcompanion. This would lead to some changes in effect sizes and their confidence intervals reported by the respective functions.
Robust one-sample test is changed from one-sample percentile bootstrap to bootstrap-t method for one-sample test, which uses trimmed mean like the rest of the robust functions in this package.
MINOR CHANGES
Package internally relies on afex instead of ez for within-subjects ANOVA.
expr_template gains paired argument.
MINOR CHANGES
Internal refactoring to catch up with changes made to effectsize. Tests are adapted to these changes as well.
Sample size information in expressions is pretty-formatted.
MAJOR CHANGES
Adds two new helper functions: tidy_model_parameters and tidy_model_performance to toggle between easystats and tidymodels naming conventions.
Drops broomExtra from dependencies in favor of parameters + performance.
Removes the unused and vestigial Titanic_full dataset.
BREAKING CHANGES
Removes the alias expr_onesample_proptest.
The expr_template function retires effsize.df argument. Now all details need to be entered only in data.
All meta-analyses are now carried out using expr_meta_random and the individual functions have been removed.
MAJOR CHANGES
All effect sizes for contingency tabs are now calculated via effectsize instead of rcompanion. This would lead to slight differences in effect sizes and their CIs but the computations will be faster. Additionally, the lower bound will never be negative and will be restricted to [0,1].
expr_contingency_tab function has been made less robust. It now fails instead of returning NULL when it is not supposed to work. This is done to be consistent with the other functions in the package which also fail instead of returning NULL.
expr_anova_parametric always applies sphericity correction for p-values for repeated measures ANOVA.
expr_anova_parametric retires non-partial variants of effect sizes (eta-squared and omega-squared, i.e.) for parametric analyses.
The t-test and ANOVA tests get subject.id argument relevant for repeated measures design.
MINOR CHANGES
Retires the vestigial stat.title argument. It was originally intended to give more info on the tests, but now the expressions themselves contain these details.
For paired ANOVA designs, partial = TRUE is recognized by effect sizes.
Retires bias.correct argument for contingency table analysis. It is rarely justifiable to use the biased version of Cramer’s V.
MINOR CHANGES
Adapts tests to changes made in the correlation package.
Subtitles for correlation tests make clear the type of statistic.
Small p-values (< 0.001) are now shown in scientific format.
MINOR CHANGES
Adapts to changes made in tidyBF package.
Re-exports correlation::correlation needed for ggstatsplot.
The expr_t_nonparametric subtitle now clarifies whether it’s a Wilcoxon test or a Mann-Whitney test.
MINOR CHANGES
Thanks to Sarah, the package has a hexsticker. :)
Confidence intervals for Spearman’s rho are computed using correlation instead of rcompanion.
All relevant functions get rid of messages argument as the functions no longer print a message when bootstrapped CIs are used.
The effect size measure for paired robust t-test is now changed to robust (trimmed-Winsorized) standardized difference similar to Cohen’s d.
BUG FIXES
0.4.0 release for expr_anova_parametric: changing conf.level doesn’t work and function defaults to 0.90 CIs (#32).MINOR CHANGES
BREAKING CHANGES
Removes the experimental corr_objects function.
All Bayes Factor related functions have now moved to the new tidyBF package and are re-exported from there.
MAJOR CHANGES
Minimum R version bumped to R 3.6.0.
Retires the internal effsize_t_parametric helper function in favor of relying functions from effectsize, which is now added as a dependency. Similarly, statsExpressions now relies on effectsize to compute effect sizes for ANOVA designs, instead of sjstats.
For parametric t-tests and ANOVAs, confidence intervals for effect sizes are estimated using the noncentrality parameter method. Centrality-based methods are deprecated.
Correlation analysis is carried out using correlation package, which is now added as a dependency.
MINOR CHANGES
corr_objects to reduce dependency load of ggstatsplot. This is an experimental function and should be avoided until it stabilizes.NEW FEATURES
expr_meta_bayes.NEW FEATURES
expr_meta_parametric, expr_meta_robust, bf_meta.BREAKING CHANGES
expr_template function now expects two dataframes: data and effsize.df that contain the details needed for creating expressions instead of providing each individual values. This makes the function more friendly work with using modeling packages like broom.MINOR CHANGES
Minor tweaks to how widehat is displayed in some of the expressions.
Cramer’s V is bias-corrected by default.
MAJOR CHANGES
Removes MCMCpack from Depends.
All effect size texts now contain ^ on top to signify that these are estimates.
MINOR CHANGES
CRAN.MINOR CHANGES
Fixing tests for the new release of rcompanion dependency.
Minor code refactoring.
