One comment only, as on questions like this I am not
qualified to be a panelist; in particular, I am not able
to answer the question about statistical validity.
In general, the option -robust-
will be available for a command if and only if the help
for that command says it is. So, if you are typing
some specific command for which -robust- is supposedly
available, please say exactly what you are typing.
