      Statistical Software.

    + Updated references in help files and package vignette.



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.
