Calculate the Satorra-Bentler Scaled Chi-Square using the loglikelihood following an Mplus ML, MLM, MLR or WLSMV
see http://www.statmodel.com/chidiff.shtml for more information. Also see a note in Mplus discussion from B. Muthén

Required commands

l0 - Loglikelihood in analysis model

l1 - Loglikelihood in the unconstrained or less constrained model

p0 - Number of parameters in the analysis model

p1 - Number of parameters in the unconstrained or less constrained model

Options

c0 c1 - Specify the scaling correction factor, default = 1

Example

. lli , l0(-2606) l1(-2583) c0(1.450) c1(1.546) p0(39) p1(47)

difference test scaling correction (cd) = 2.014

Chi-square difference test = 22.840

P = 0.004
