Plot parameter differences — plotParDiffTree • semtree

Visualizes parameter differences between post-split nodes with different plot types.

plotParDiffTree(
  tree,
  plot = "ballon",
  measure = "wald",
  normalize = FALSE,
  title = TRUE,
  structure = FALSE
)

Arguments

tree: a semtree object.
plot: a character that specifies the plot typ. Available plot types are "ballon" (default), "heatmap", and "bar".
measure: 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.
normalize: logical value; if TRUE parameter differences of each split are divided by sum of all differences the corresponding split. Set to FALSE by default.
title: logical value; if TRUE a title is added to the plot.
structure: logical value; if TRUE the structure of the tree is plotted on the right side.
