Satorra-Bentler corrected chi-square test

Description

Computes Satorra-Bentler corrected chi-square test.

Usage

chisq_sb(chisq1, df1, scf1 = 1, chisq2, df2, scf2 = 1)

Arguments

chisq1	An object for which a method exists; e.g., a chi-square value, or a data.frame.
df1	Degrees of freedom of model 1.
scf1	Scale correction factor of model 1.
chisq2	Chi square value of model 2.
df2	Degrees of freedom of model 2.
scf2	Scale correction factor of model 2.
