Weighted significance tests have been re-designed. The functions weighted_ttest(), weighted_mannwhitney() and weighted_chisqtest() are no longer available. These are now re-implemented in t_test(), mann_whitney_test() and chi_squared_test(). If weights are required, the weights argument can be used. Furthermore, new functions for significance testing were added: kruskal_wallis_test() and wilcoxon_test().
means_by_group() and mean_n() were removed. The replacements are datawizard::means_by_group() and datawizard::row_means() (using the min_valid argument).
weighted_median(), weighted_sd() and weighted_mean() were removed. Their replacements are datawizard::weighted_median(), datawizard::weighted_sd() and datawizard::weighted_mean().
Package dependency was dramatically reduced. sjstats now requires much fewer and much more light-weight packages to work.
Some minor bugs were fixed.
sjstats is being re-structured, and many functions are re-implemented in new packages that are part of a new project called easystats.
Therefore, following functions are now defunct:
mediation(), , please use bayestestR::mediation().eta_sq(), please use effectsize::eta_squared().omega_sq(), please use effectsize::omega_squared().epsilon_sq(), please use effectsize::epsilon_squared().odds_to_rr(), please use effectsize::oddsratio_to_riskratio().std_beta(), please use effectsize::standardize_parameters().robust(), please use parameters::standard_error_robust().scale_weights(), , please use datawizard::rescale_weights().Improved printing for weighted_mannwhitney().
weighted_chisqtest() can now be computed for given probabilities.
means_by_group() now contains numeric values in the returned data frame. Value formatting is completely done insight the print-method.
Updated imports.
eta_sq()) now internally call the related functions from the effectsize package.chisq_gof().anova_stats() with incorrect effect sizes for certain Anova types (that included an intercept).sjstats is being re-structured, and many functions are re-implemented in new packages that are part of a new project called easystats.

The aim of easystats is to provide a unifying and consistent framework to tame, discipline and harness the scary R statistics and their pesky models.
Therefore, following functions are now deprecated:
p_value(), please use parameters::p_value()
se(), please use parameters::standard_error()
design_effect() is an alias for deff().samplesize_mixed() is an alias for smpsize_lmm().crosstable_statistics() is an alias for xtab_statistics().svyglm.zip() to fit zero-inflated Poisson models for survey-designs.epsilon_sq(), to compute epsilon-squared effect-size.sjstats is being re-structured, and many functions are re-implemented in new packages that are part of a new project called easystats.
