)a semforest object.
a character that specifies the plot typ. Available plot types are "boxplot" (default) and "jitter" for a jittered strip plot with mean and standard deviation.
a character. "wald" (default) gives the squared parameter differences divided by their pooled standard errors. "test" gives the contributions of the parameters to the test statistic. "raw" gives the absolute values of the parameter differences.
logical value; if TRUE parameter differences of each split are divided by sum of all differences the corresponding split. Set to FALSE by default.
a character. Select predictors that are to be plotted.
logical value; if TRUE a title is added to the plot.
