In fungible: Psychometric Functions from the Waller Lab

Calculate CFI for two correlation matrices

Description

Given two correlation matrices of the same dimension, calculate the CFI value value using the independence model as the null model.

Usage

cfi(Sigma, Omega)

Arguments

Sigma	(matrix) Population correlation or covariance matrix (with model error).
Omega	(matrix) Model-implied population correlation or covariance matrix.

Examples

library(fungible)

mod <- fungible::simFA(Model = list(NFac = 3),
                       Seed = 42)
set.seed(42)
Omega <- mod$Rpop
Sigma <- noisemaker(
  mod = mod,
  method = "CB",
  target_rmsea = 0.05
)$Sigma
cfi(Sigma, Omega)
