CRAN release: 2023-05-23

MAJOR CHANGES

  • Following dependencies move from being weak to strong dependencies given their importance in key functions: afex and {PMCMRplus}.

statsExpressions 1.5.0

CRAN release: 2023-02-19

BREAKING CHANGES

  • The minimum needed R version is now bumped to R 4.1 because a critical dependency (pbkrtest) requires this R version.

statsExpressions 1.4.0

CRAN release: 2023-01-14

NEW FEATURES

  • All returned data frames from statsExpressions get a new statsExpressions class and a print method for this class.

MINOR CHANGES

  • Maintenance release.

statsExpressions 1.3.5

CRAN release: 2022-11-07

  • centrality_description() gets a new conf.level parameter.

  • Updates tests and examples to insure against removal of suggested packages.

statsExpressions 1.3.4

CRAN release: 2022-10-10

  • Fixes breakages due to effectsize package update.

statsExpressions 1.3.3

CRAN release: 2022-08-11

MINOR CHANGES

  • When any of the necessary numeric column values are missing, for these rows tidy_model_expressions() now returns a NULL instead of an expression with empty strings.

statsExpressions 1.3.2

CRAN release: 2022-05-20

NEW FEATURES

MAJOR CHANGES

  • Expressions with statistical details were sometimes in a column named label, while other times in expression column. Now it will be consistently in the expression column.

  • Additionally, glue expressions were stored parsed in some data frame outputs, while unparsed in others. Now it is consistently parsed.

  • The top.text parameter has been removed from all functions. It was relevant only in the context of ggstatsplot package. As that package no longer uses it, it is no longer necessary to retain it.

statsExpressions 1.3.1

CRAN release: 2022-03-29

  • Fixes breakages due to insight package update.

statsExpressions 1.3.0

CRAN release: 2022-01-14

BREAKING CHANGES

MINOR CHANGES

  • The expr_template() has been renamed to more informative add_expression_col() function and has a different API. It returns a dataframe with the additional expression column instead of just the expression.

statsExpressions 1.2.0

CRAN release: 2021-10-19

BREAKING CHANGES

  • A number of effect size estimates and their confidence intervals have changed due to respective changes made in effectsize package version 0.5 release. For full details of these changes, see: https://easystats.github.io/effectsize/news/index.html

  • For the same reason, the effect size for one-way contingency table has changed from Cramer’s V to Pearson’s C.

NEW FEATURES

  • centrality_description() function added to describe distribution for each level of a grouping variable and create an expression describing a centrality measure.

  • Adds new experimental function tidy_model_expressions() to create expressions for dataframes containing tidied results from regression model objects.

MAJOR CHANGES

  • Removes the redundant bf_extractor function. The tidy_model_parameters does the same thing.

  • Exports more utility functions (long_to_wide_converter, format_num, stats_type_switch) to get rid of reliance on ipmisc package.

  • To be consistent with the expressions, the dataframe for Bayesian analysis now also contain log of Bayes Factor values.

  • The tidy_model_effectsize() function is no longer exported as it is helpful only for the internal workings of the package.

  • Given that these values can be really high, the statistic values for non-parametric tests were shown on a log scale, but this is a highly non-standard practice that has caused a lot of confusion among users. In light of this feedback, the functions no longer return these values on a log scale but in a scientific notation to keep the statistical expressions short.

MINOR CHANGES

  • Removes VR_dilemma dataset, which lacked enough variation to be a good dataset to use in examples or tests.

statsExpressions 1.1.0

CRAN release: 2021-05-30

MAJOR CHANGES

  • There is a new JOSS paper about statsExpressions package!! https://joss.theoj.org/papers/10.21105/joss.03236

  • The effect size for independent trimmed means two-sample test has been changed from explanatory measure of effect size to AKP’s delta, which is easier to understand and interpret since its a robust cousin of Cohen’s d.

  • one_sample_test and two_sample_test gain alternative argument to specify alternative hypothesis (#86).

  • Cohen’s d and Hedge’s g use non-pooled standard deviation (cf. https://psyarxiv.com/tu6mp/).

MINOR CHANGES

  • The output dataframes now contain columns with additional information about how confidence intervals are computed (thanks to effectsize package).

statsExpressions 1.0.1

CRAN release: 2021-04-13

BREAKING CHANGES

  • Retires all vestigial expr_* functions.

MINOR CHANGES

  • Adapts failing tests due to changes in effectsize.

statsExpressions 1.0.0

CRAN release: 2021-03-11

This is the first stable release of statsExpressions!

There is good news and there is bad news that accompanies this milestone.

  • The bad news: The API for the package has changed completely: All functions return a dataframe, and not an expression, as a default. The expression is contained in a list column in the dataframe itself. So, to salvage your functions from breaking, you will have to add $expression[[1]] to your function calls. For example, if you were using the function expr_t_onesample(), you will now have to specify expr_t_onesample()$expression[[1]], so on and so forth. But, in general, the advice is to not use any of the expr_* functions, which are vestigial names for new avatars of these function and will be removed in future. The new names are more intuitive, e.g., expr_t_onesample() is now called one_sample_test(), etc.

  • The good news: There will not be any new changes to any of the current functions, except for any change necessary for maintenance or bug squashing. Well, to be more precise, this is true only for the functions that have “stable” badge.

BUG FIXES

  • If the entered dataframe is grouped-tibble, the function internally ungroups this (#79).

MINOR CHANGES

  • To reduce dependency load, afex has moved from Imports to Suggests.

statsExpressions 0.7.1

CRAN release: 2021-02-19

BREAKING CHANGES

  • To avoid confusion among users, the trimming level for all functions is now changed from 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.

statsExpressions 0.7.0

CRAN release: 2021-01-19

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.

    • t_parametric, t_nonparametric, t_robust, t_bayes are now removed in favor of a single function two_sample_test.

    • expr_anova_parametric, expr_anova_nonparametric, expr_anova_robust, expr_anova_bayes are now removed in favor of a single function 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

  • contingency_table 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.

statsExpressions 0.6.2

CRAN release: 2020-12-08

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.

statsExpressions 0.6.1

CRAN release: 2020-12-01

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.

statsExpressions 0.6.0

CRAN release: 2020-10-30

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].

  • contingency_table 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.

statsExpressions 0.5.1

CRAN release: 2020-10-05

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.

statsExpressions 0.5.0

CRAN release: 2020-09-12

MINOR CHANGES

  • Adapts to changes made in tidyBF package.

  • Re-exports correlation::correlation needed for ggstatsplot.

  • The t_nonparametric subtitle now clarifies whether it’s a Wilcoxon test or a Mann-Whitney test.

statsExpressions 0.4.2

CRAN release: 2020-06-20

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.

statsExpressions 0.4.1

CRAN release: 2020-04-22

BUG FIXES

  • Major bug introduced in 0.4.0 release for expr_anova_parametric: changing conf.level doesn’t work and function defaults to 0.90 CIs (#32).

MINOR CHANGES

  • Removes extra space contained in subtitles for Bayes Factor results (#31).

statsExpressions 0.4.0

CRAN release: 2020-04-15

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

  • All expressions now contain name of the statistical test carried out.

statsExpressions 0.3.1

CRAN release: 2020-02-14

NEW FEATURES

  • Adds a new function corr_objects to reduce dependency load of ggstatsplot. This is an experimental function and should be avoided until it stabilizes.

statsExpressions 0.3.0

CRAN release: 2020-01-29

NEW FEATURES

  • New function to carry out meta-analysis: expr_meta_bayes.

statsExpressions 0.2.1

CRAN release: 2020-01-23

NEW FEATURES

  • New function to carry out meta-analysis: expr_meta_parametric, expr_meta_robust, bf_meta.

statsExpressions 0.2.0

CRAN release: 2020-01-10

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.

statsExpressions 0.1.3

CRAN release: 2019-12-18

MAJOR CHANGES
