Constrained MLE of fixed mean Singh-Maddala distribution
...la (Burr)
distribution. The final model will fix the mean of the distribution to a
given value and estimate the remaining parameters accordingly; however,
the code provided below ignores this. For this distribution the three
parameters ('a': corresponding to 'a' in the function 'dsinmad' under
the package 'VGAM'; 'b': corresponding to 'scale'; and 'q':
corresponding to 'q.arg') are constrained to be strictly positive. For
this I estimate parameters, first using 'optim' (and later 'nlm'),
defined over the set of real numbe...
