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.
