In my study, I need to compare the nested model and the comparison model to test the parameter's invariance of the SEM. Because of the non-normality, I manually calculate the chi square difference and df difference, but I don't know how to calculate the p value. Therefore, in sas, how to use the syntax to calculate the p value of the corresponding chi square difference and df difference. There is no data.
Here is the syntax I used, but the system presented some errors.
Thank you in advance! Any response is really appreciated.
