Hmm, one of the acronym definition pages on the web says
>> Acronym Definition
>> HCCM Healthcare Continuum Model
>> HCCM Discharge Under Honorable Conditions, Convenience of the Man
But let's assume you mean heteroscedasticity correction as
provided e.g. by package 'sandwich'.
Note that using that *not* robust estimation in the sense of
most people reading this mailing list.
But now to the topic of 'Deducer' vs 'Rcmdr' (note: Subject amended: "+r") :
One reason 'Rcmdr' has been quite nice for teaching has been
that you can somewhat easily *modify* it,
by adding your own menu entries; modify or even omit existing ones.
How easy is that with 'Deducer' ?
