This happens in gretl 1.5.1 and the latest snapshot (6.1.2006),
(windows version):
1- First, I run a high precision regression: mpols y 0 x
2- I run: genr cfx = $coeff(x) to get the internal variable and
command returns no comments (no errors or messages saying scalar cfx
generated)
3- Consequently, running "print cfx" returns an error saying no
variable named cfx.
4- Next, I run a regular ols this time: ols y 0 x
5- Running genr cfx = $coeff(x) creates the scalar OK this time and I
can see the value using the "print cfx" command.
6- Now, I run the initial high precision regression once again: mpols
y 0 x and suprisingly running genr cfx = $coeff(x) suddenly starts
working by giving the message "replaced scalar cfx ..."
7- Finally, after running a mpols and running genr to get $uhat,
$yhat, $stderr, $rho, $vcv also return no feedback (as described
above) while $T, $rsq, $ess, $df, $ncoeff, $trsq, $sigma, $aic, $bic,
$lnl return "The statistic you requested is not available. On the
other hand $nobs, $pd, $nvars, $test, $pvalue seem to work OK with the
genr command after running the mpols.
