regression diagnostics

[kamaraju kusumanchi]

>From octave's manual, I see that ols function performs ordinary least
squares. Does octave provide any regression diagnostic tools (ex:-
computation of t-stats, standard error, r-square value, adjusted
r-square value etc.,). Currently I am coding these by myself. But just
wondering if the tools are already there or if they are planned in
future versions.

Using octave 3.2.4 on Debian squeeze.
