Hey Allin,

I should have been more precise.
Actually I am trying to replicate figure 2a (std. deviation of the permanent component) and 2b (std. deviation of the transitory component) from the S/W paper.

If one compares figures 2a and 2b with the results I've obtained with Peter Summer's gretl code (pdf, attached before) you see that they highly deviate from Stock and Watson's results. But using the original code I can replicate their figures quite well (see attached pdf files).

I thought that maybe somebody on the mailing list has already tried to replicate the S/W paper using their data and Peter Summer's code.

Best,
Artur

What exactly is it that you're comparing between the Stock &
Watson paper and gretl output? And are you using the corrected
S & W output?
