Take a look at the script perron97.inp -- it's under /File/Script
files/Practice file and the "Gretl" tab.

Well we're not at a Star Trek level yet where you talk to gretl and say
"gretl, please run this test for me, you know what I mean". So you need
to learn how to use it. Start reading the documentation.
Apart from that, if you understand that Perron test and if I remember
the test correctly (which by the way doesn't test the break but instead
tests for a unit root _allowing_ for a break), then you can implement it
in the graphical interface as well, it's just a regression with suitable
right-hand side variables.
The only thing that perhaps is not doable with the mouse alone is to
construct the break dummy. Not sure if now there exists a function
package that makes it easier to construct such a dummy in the GUI. (->
question to all)
cheers,

That should be doable via "/Add/Observation range dummy" in the main
gretl window.

Ah, of course! Maybe I should change the German translation for that, I
don't understand it myself... (not easy to find something better though).

I'm going to surprise you with a secret we've managed to keep for years:
gretl comes with a fine set of assorted manuals. Since we wanted nobody to
know of their existence, we stashed them in a place where nobody would
even think of looking: the "Help" menu. There, I said it.
