Thanks for the suggestion.
In fact, no formal 'relationship' between S and a -- the use is merely
symbolic (verging on straight aesthetics). I have a parameter S which
takes in different values for different classes of 'individuals' in the
sample -- so, S_a, s_o, S_j etc....
What I had often done (with Maple) is throw all the parameters in a
vector S, and used the subscript to 'call' them. The implicitdiff
function in Maple has no problem with this (note: not a complaint about
Maxima in any form -- I'm just trying to suss out the easiest way to
proceed).
