Dear Allin,
Note that Windows 8 gives absolutely the same visible
digits as Linux. Also, these estimates have at least 4
coinciding digits in comparison with using --x-12-arima
In contrast, for the constant we have 10% difference
between Windows 10 and (the same) Linux, Windows 8,
and (almost the same --x-12-arima).
So it is very unlikely due to rounding errors.
Also, I used --verbose option: the initialization steps
were different on Windows 10.
I think, it may be more convenient to compare Windows 8 (which is obviously
correct)
and Windows 10: they have more in common in comparison with Linux.
Comparing Windows 8 with Windows 10 is not meaningful unless you're
using exactly the same gretl package on both platforms (same
build-date, same word-length): I update my cross-compilers for
32-bit and 64-bit Windows from time to time, and also update the
OpenBLAS sources from time to time. And I'm not in a position to
test on Windows 8 any more, though I can test on Windows 10; I'll do
so when I next get a chance.
