[Gretl-devel] Re: tobit's --quiet flag to quite guiet

Hi,
when we perform tobit command with --guiet flag we sometimes get the
following message: "Warning: couldn't improve criterion (gradient =
6.04477e-06)", which /per se/ makes estimation not so quiet. So, the
question is: shall we leave current behavior or make 'tobit --quiet'
really quiet?
If the later, I wrote a simple patch which suppress any messages
(attached). Another possibility would be adding '--silent' flag, which
I could do either?
Personally I think that choosing "quiet" doesn't mean that I
don't want
to see warning messages, so the current behavior is OK. "silent" could
be a possibility, but then I think we would have to do it for all
estimators, not just for tobit out of coincidence. Right now I think the
guideline is more or less that "silent" exists for tests and for system
estimation (where even quiet prints a little bit of regular output).
I believe there's a workaround to really suppress all output: Wrap it in
an "outfile" block:
string temp
outfile --buffer=temp
tobit ...
outfile end
And simply discard the string. Admittedly not very elegant...
