Testing for variance-inhomogeneity using Breauch-Pagan test for each comparison

Description

Testing for variance-inhomogeneity using Breauch-Pagan test for each comparison

Usage

heteroscedasticity_test(
  data,
  alpha = 0.05,
  groups = "Comparison",
  bonferroni_correct = FALSE,
  conservative = TRUE,
  robust = TRUE
)

Arguments

data	A data table or data frame of type LFDT grouped according to groups
alpha	The base significance level of the test.
groups	The names of grouping columns in data
bonferroni_correct	Should we Bonferroni correct the significance level based the number of MS comparisons. Default is TRUE
conservative	Should the Bonferroni correction be done conservatively that assumes that some of the MS comparisons are dependent? Default is TRUE
robust	Should Koenker's adjust be implemented in the test? Recommended if data is non-normal. Default is TRUE

A data table with grouping as the first column, LM test statistic as the second column, p-value as the third column, and judgement as the last column
