In mirka-henninger/raschTreeEffectSize: Helper functions to use the Mantel-Haenszel effect size measure as a stopping criterion in Rasch trees

Description

Performs classification of the Mantel-Haenszel effect size measured based on ETS guidelines see Dorans & Holland, 1993, p. 41f or Paek & Holland, 2015, Psychometrika

Usage

get_ETS_classification(res_MH, res_MH_sd)

Arguments

res_MH	A vector or dataframe with the Mantel-Haenszel Odds Ratio effect size measure in the Delta scale (-2.35 * log (Mantel-Haenszel estimate of the common odds ratios)) for each item
res_MH_sd	A vector or dataframe with the standard deviation of Mantel-Haenszel Odds Ratio effect size measure in the Delta scale for each item (-2.35 * sqrt (the variance of the lambda_MH statistic))

Value

A vector or dataframe with the corresponding A/B/C classification for each item Computes p-values for the statistical hypothesis testing based on log transformation of the Mantel-Haenszel common odds ratio in the Delta-scale for DIF p values of the hypothesis test are need for the classification of DIF items based on the ETS guidelines based on Paek & Holland, 2015, Psychometrika
