I am testing a path model with WLSMV estimator and brr replicate weights. As I didn't get chi-square related fit index with brr replicate weights, I have created an adjusted chi-square statistic by applying design effect with chi-square value from conventional analysis as Stapleton did so (2008).
My question is I have used WLSMV estimator to get indirect effects between variables and I wonder how I can get chi-square difference test with this adjusted chi-square value. With diff test from conventional analysis, can I use test result for my test model with replicate weights? Or is there any other way that I can manually test chi-square difference test with adjusted chi-square statistic?
I computed CFI, TLI and RMSEA with this adjusted chi-square, and those fit indice are very similar to those from conventional analysis. My fit indice are CFI=0.987, TLI=0.973, and RMSEA=0.042 with adjusted chi-square statistic.
