getCFI.Sigma.mgroups: getCFI.Sigma.mgroups

In semPower: Power Analyses for SEM

getCFI.Sigma.mgroups

Description

Computes CFI given the model-implied and the observed (or population) covariance matrix for multiple group models. CFI = (F_null - F_hyp) / F_null applying multiple group sampling weights to F_hyp and F_null.

Usage

getCFI.Sigma.mgroups(
  SigmaHat,
  S,
  muHat = NULL,
  mu = NULL,
  N,
  fittingFunction = "ML"
)

Arguments

SigmaHat	a list of model implied covariance matrix
S	a list of observed (or population) covariance matrix
muHat	model implied mean vector
mu	observed (or population) mean vector
N	a list of group weights
fittingFunction	whether to use ML or WLS

Value

Returns CFI
