Heckit model "rho"
by Brian Starr
I'm trying to determine what the "rho" metric reported at the bottom of the Heckman chart is measuring and can't find it referenced in the User's Guide. Any guidance would be appreciated.
Thanks,

In loop list modification
by Itai Zohar
Hi all,
In process of learning the gretl programming interface I'm trying to
write a stepwise regression procedure (btw, does this exist already?),
and encounter strange results when I apply the -= operation to a list
within a loop. So outside of a loop when I execute:
xlist -= Z2
the Z2 variable is removed from the list xlist. Inside a loop,
however, xlist only contains Z2 and not the other variables. I'm sorry
if this has been posed before -- I just joined the group -- but what
is the correct way to remove a variable from a list inside a loop?
(That attached code demonstrates the point)
Thanks!
Itai.

Gretl and X-12-ARIMA and TRAMO/SEATS
by deriv＠libero.it
Dear all,
I just downloaded Gretl for Windows and the X-12-ARIMA and TRAMO/SEATS
software but I cannot reach these last programms from the "Variable" menu in
Gretl.
I just run the self-installer file for both of them. Do I have to choose a
particular directory where to download the programms?
Thank you all.
Regards.

figure, --loess-fit and loop
by artur tarassow
Hello,
when I try to generate a xy-plot with the "--loess-fit" option using
the loop command
foreach i 6 10 100
gnuplot hph_$i hpwa_lab_$i --loess-fit --output=hp_h_wa_lab_$i.eps
endloop
the compiled files will be corrupted. For the other "fit"-options it works well.
Is there a reason for this?
Best,
Artur
