Sorry that I wasn't clear. I'm looking for how to do things
using
the menu based version. That is, where can I click on to get the
aggregate or the means by group, using the menu drop downs?
There's a new feature and a fix in the gretl source code (not yet in
snapshots for Windows and Mac, but they'll follow soon).
* Feature: the "Summary statistics" item under the "View" menu in
the main gretl window now branches into "plain" and "factorized". In
the factorized case you're asked to select a "primary" variable and
a factor, and you get summary statistics for the primary one "by"
the values of the factor. In effect, this enables GUI access to the
"--by" option to the "summary" command as mentioned by Sven.
* Fix: when you invoke a "factorized boxplot" (also mentioned by
Sven) the window that displays the plot has a right-click menu
including the item "Numerical summary". This ought to provide quick
access to basic summary stats by value of the factor, but it was
broken for the case where the factor variable is string-valued (like
AreaRegion in your test data file). You'd get the message "Data
error". That's now fixed.
