求助 Stata gsem的goodness-of-fit test

软件STATA 14.0, 使用gsem是因为我的结构方程模型包括了多层变量(clustering),所以需要做multi-level modelling。最终的gsem按照性别区分（就是男性一个model，女性一个model）。有三个问题请教：1. 看到说明说gsem无法给出standardized regression coefficient, 是否可以通过其他方式获得？
2. 运行完gsem后，我想看它的goodness-of-fit，主要是想看RMSEA和CFI这两个指标。但是用estat gof, stats(all)返回是”subcommand estat gof is unrecognized“，请问应该怎么办？
3.另外想求一篇写的比较好的使用了gsem的英文学术文章（IF比较高的，最好是医学健康或心理测量领域）来学习一下怎么写gsem部分的研究方法、结果和path diagram。
论坛币不多，请知道的前辈不吝请教。

1. gsem can not produce standardized coefficients

2. Gof statistics only can be obtained in sem instead of gsem. In gsem, you can try estat ic command to have Akaike and Bayesian information criteria.

3. Statistical models for multilevel skewed physical activity data in health research and behavioral medicine.
