I have a non-normal data for which I used satorra-bentler chi square. The problem I am facing is in testing the measurement invariance of a second-order factor model in lisrel. Unfortunately, the lisrel tutorial only shows examples of first order factor models and there is hardly any mention of second order factor models. Getting through configural and metric is somewhat comprehensible, but testing scalar invariance is a tricky job. Can anybody provide me the syntax to carry out a scalar invariance please? Any suggestion would help me move ahead with this problem.
