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