In SBSDiff: Satorra-Bentler Scaled Chi-Squared Difference Test

Description

Takes chi-squared values from nested models estimated using maximum likelihood with robust standard errors, model degrees of freedom, scaling correlation factors and returns: (1) change in model chi-squared (2) change in model degrees of freedom and (3) the probability of rejecting the null.

Usage

sbs.chi(chi0, chi1, df0, df1, c0, c1)

Arguments

chi0	chi-squared value for the more restrictive model
chi1	chi-squared value for the less restrictive model
df0	degrees of freedom for the more restrictive model (with more degrees of freedom)
df1	degrees of freedom for the less restrictive model (with fewer degrees of freedom)
c0	scaling correction factor for the more restrictive model
c1	scaling correction factor for the less restrictive model

Value

Change in model chi-squared, change in model degrees of freedom and the probability of rejecting the null

Examples

chi0 <- 50

chi1 <- 40

df0 <- 10

df1 <- 9

c0 <- 1

c1 <- 1

sbs.chi(chi0,chi1,df0,df1,c0,c1)
