Hi all,
I have found a discussion from last December about performing the
Bai-Perron test for structural changes in Gretl.
Eventually it was suggested to exploit Gretl’s link to R and do this test
using the strucchange package for R. Could someone help me in doing this? I
am far to be defined an expert in coding and programming… Thank you so much
Stefano
(I copy and paste below the discussion that I have found in the archive – I
was not part of the mailing list at the time).

I have no idea. :D
I wrote the code a while back, used it for what I needed it, and then
become abandonware. I'll send you a zipfile privately.

I'm not sure if Jack really sent the file, I haven't found the
corresponding email. As I had said back then, I could try to write a
wrapper around Jack's code. But before I see his actual code, I cannot
promise anything.
cheers,

Jack has sent me his latest version (and he had actually sent something
back in December, I forgot about it).
In principle this should be interesting, but currently I have very
little time...
Feel free to remind me in a couple of weeks.
cheers,
sven
