I try to compare the means of a latent construct across two groups. All observed variables are binary. I use WLS as estimator. The results make sense as the mean of the reference group is 0 and the mean of another group is .34. But the standard error is computed and is listed as ******. Did I do something wrong? Curiously, when I change the estimator to either WLSM or WLSMV, I was told that my model may be misspeified. But with WLS no such warning is issued. Lianjiang Li Hong Kong Baptist University |

I'm sure other users won't make the mistake that I made, but I'd like to post Professor Linda Muthen's response to my inquiry for the record. I, of course, am very grateful for her kindness. Lianjiang Li Hong Kong Baptist University Here is Professor Muthen's message: Lianjiang, The problem with you model is that you have not set the metric of the factor. To do this, you need to allow one factor loading to be fixed at one or fix the variance of the factor to one. I have fixed the variance of the factor at one and attach the output. Please let me know if you have any other questions. Linda |
