Description

options for test_itemfit()

Usage

itemfit_control(
  zstd = FALSE,
  msq = TRUE,
  outfits = TRUE,
  use.pval = TRUE,
  lowerMSQ = 0.7,
  upperMSQ = 1.3,
  lowerZ = -1.96,
  upperZ = 1.96,
  use.rel = FALSE
)

Arguments

zstd	a boolean value whether to check the standardised fit indices
msq	a boolean value whether to check the mean-squared fit indices
outfits	a boolean value whether to check outfit indices (if FALSE, only infits are checked)
use.pval	a boolean value whether to exclude combinations with at least one item with significant p-value
lowerMSQ	a numeric value for the lower bound for acceptable fit (mean-squared fit indices)
upperMSQ	a numeric value for the upper bound for acceptable fit (mean-squared fit indices)
lowerZ	a numeric value for the lower bound for acceptable fit (standardised fit indices)
upperZ	a numeric value for the upper bound for acceptable fit (standardised fit indices)
use.rel	a boolean value wheter to use the unweighted (default, FALSE) or weighted item fit indices for MSQ and z-standardised fit-indices. Only available for 'pairwise' and 'psychotools' estiomation, will be ignored, for 'eRm' estimation.
