Changes in robmed version 0.11.0 + Added function sim_mediation() and wrapper rmediation() to generate data from a fitted mediation model. + Updated documentation of fit_mediation() and test_mediation() with a brief description of the implemented mediation models. + Updated and added more examples in help files. + Updated the help file of the BSG2014 data with more details on the measurement scales of the variables. + Updated package vignette. Changes in robmed version 0.10.1 + Updated package vignette. Changes in robmed version 0.10.0 + Added package vignette. + Added support for the serial multiple mediator model in bootstrap tests based on regressions. + Moved shiny app in separate package 'robmedShiny': https://github.com/aalfons/robmedShiny + Updated BSG2014 data with more variables. + Updated examples. + Removed superfluous package MASS from Suggests. Changes in robmed version 0.9.0 + Updated package dependencies. + retest() now uses values of original object as defaults for arguments that are not supplied. + Added argument 'contrast' to fit_mediation() and test_mediation(), which allows to test for differences of (absolute values) of indirect effects. + Bugfix in plots: order of different models, effects or methods is preserved with R >= 4.0.0 (where data.frame() by default no longer converts character strings to factors). + Added support for multiple independent variables to be mediated in bootstrap tests based on regressions. + Removed demos from package. Changes in robmed version 0.8.0 + Changes in class structure regarding how effects are stored. + Added more unit tests. + Bugfix in setup_density_plot(): in case of multiple indirect effects, the column "Effect" of the data frames is now a factor to preserve the order in the plot. + Bugfix in setup_ellipse_plot() regarding checks of variables to be plotted on vertical and horizontal axis. + Added functions setup_weight_plot() and weight_plot() to produce a diagnostic plot of robust regression weights. + summary() method for robust boostrap tests with MM-regressions now by default produces a diagnostic plot of robust regresssion weights. Changes in robmed version 0.7.0 + Removed deprecated functions and arguments. + fit_mediation() and test_mediation() now allow to fit regression models with skew-normal, t or skew-t error distribtions. + p_value() now offers functionality in line with coef() and confint(), but default behavior is kept for back-compatibility with previous versions. + setup_ci_plot() and ci_plot() now allow to include information on p-values in addition to confidence intervals. Changes in robmed version 0.6.0 + Added formula interface. + fit_mediation() now checks for variable type rather than converting all variables to numeric. + fit_mediation() and test_mediation() now use 'robust = "median"' instead of argument 'median'. + Renamed argument 'other' for type of confidence intervals to 'type' and also changed possible values to match argument for extracting coefficients. + New plot function ellipse_plot() for a diagnostic plot with a tolerance ellipse. + dot_plot() has been renamed to ci_plot() and is now creating panels for different effects instead of different methods. + density_plot() now uses argument 'fill' only for the filled rectangle that illustrates the confidence interval, and allows to customize the transparency of the confidence interval via argument 'alpha'. + Bugfix in density_plot(): avoids that duplicated or unknown arguments are passed to geom()'s via the ... argument. + Functions ci_plot() and density_plot() are now exported and replace plot_mediation(). + New functions setup_ci_plot(), setup_density_plot() and setup_ellipse_plot() to extract relevant information for plots. + fortify() and plot_mediation() are now deprecated. + Updated demos for empirical cases 2 and 3. Changes in robmed version 0.5.0 + Changed components 'c' and 'c_prime' to 'direct' and 'total', respectively, to avoid confusion with different notation in different papers. + Removed deprecated functions. Changes in robmed version 0.4.0 + Output of summaries restructured to be similar to PROCESS macro of Andrew Hayes. + Wrapper function indirect() is now deprecated. + Added missing reference in help file of example data. Changes in robmed version 0.3.0 + Added method based on median regressions (Yuan & MacKinnon, 2014). Changes in robmed version 0.2.0 + Added shiny app for comparing bootstrap methods on simulated data with outliers. + Added support for multiple mediators for standard and robust bootstrap tests based on regressions. + Redesigned functions to live in the tidyverse: using under_scores instead of camelCase; first argument of fit_mediation() and test_mediation() is a data frame. + Added method based on robust regressions and fast and robust bootstrap, which is the new default method. + Wrapper function indirect() now always uses the bootstrap test Changes in robmed version 0.1.1 + Bugfix in density plot: bootstrap replicates for indirect effect are now correctly extracted.
