I am attempting a BSEM for categorical data with crossloadings for the first time. How do I set priors for this data which is largely skewed?12 items ordinal 0-5 scoring(psych outcome complex items). A CFA fit well with two crossloading items. I attempted to put this in a Bifactor CFA but saw I should not have crossloaders in bifactor CFA so I would like to use BSEM. I followed your examples using '~ N(0.1, 0.01)' for priors but I'm not sure if this is appropriate here.
Yes, that prior is an ok choice. Large cross-loadings will show up as significant estimates and you can then free them if you want. But try some other variance values as well (smaller and larger) and see how it affects results.
