A few things to report:
1) Jack has added Interval regression, the shiny new "intreg"
command. It's documented and in the GUI and has an example
script.
2) I've just done something that was requested a while back,
namely enabled the "restrict" command for nls, mle and gmm.
Please test and report any misbehavior!
3) I've added accessors $Fstat and $chisq which retrieve the
F-stat or chi-square test for overall fit from the last model.
(Most model types have an Fstat but no chisq; the exception
is the limited-dependent variable models logit, probit and
intreg.)
There will be a few new translatable strings in connection with
intreg; I'll update gretl.pot shortly.
Allin.
