You should also look at the help files for - mi estimate - and the individual commands you are interested in.  Although post-estimation commands exist for some of the procedures you are interested in using, it is possible that there is little, or no, support regarding their performance with imputed data.  In the case where some of the functions are not available, it may be helpful to find some literature that supports using that specific method with imputed data.

User-written commands are another matter. It may be that the programmer didn't know how to add mi support or that the command was written before mi became available.
