eqMI.RMSEA: Obtain the RMSEA cutoff values for equivalence testing

Description Usage Arguments Details Value References Examples

View source: R/eqMI.RMSEA.R

Description

Generate adjusted cutoff values of RMSEA for equivalence testing corresponding to conventional cutoff values .01, .05, .08, and .10.

Usage

1
eqMI.RMSEA(N, m, df)

Arguments

N

Total sample size of all groups

m

Number of groups

df

Degree of freedom

Details

The adjusted cutoff values of RMSEA for equivalence testing can be obtained with N, m, df and transformed variables. Formulas are estimated using simulation studies and the coefficients are given in Table 11 of the reference.

Value

The adjusted cutoff values corresponding to conventional cutoff values .01, .05, .08, and .10.
