Hi
I am new to Gretl so still a very basic user. From the Function Reference
help menu, I saw there is a ljungbox function. I would like to use this but
when I enter the function into the console window using the series name and
lag, nothing is returned, just a blank line. The same happens with other
functions listed under Statistical in the help menu. I have looked through
all the help menus and manuals but can't find guidance on how to run these
functions. Please provide instruction for how to use these functions.
Thanks
Leon

Functions provide a result that you can either store into a variable, or
display via the "eval" command.
For example, try the following code:
<hansl>
open np
scalar foo = ljungbox(money, 4)
print foo
### or altenatively, if you just waht to print it out
eval ljungbox(money, 4)
</hansl>
If you have a recent versione of gretl, "=" is a handy synonym for
"eval",
as in
<hansl>
=ljungbox(money, 4)
</hansl>

Functions provide a result that you can either store into a variable, or
display via the "eval" command.
I'm wondering whether the function/console usage is really wanted here.
To just see the autocorrelations of a time series and the associated
test statistics in the graphical gretl program, go to the "Variable"
menu and choose "Correlogram" (or its respective translation).
Alternatively, right-click on the series with the mouse.
