May I know what went wrong here? Your help is greatly appreciated.
Hi,
in hansl the matrix indices start at 1, not at zero, so that's the
error. Apparently here k=1, so k-1=0.
How can k=1 happen? Looking at the code (SVAR 0.994 shipped with my
gretl version) of 'init_C' shows that 'k=cols(Ss)', so the matrix
'Ss'
must have zero columns.
Now Ss is created by 'Ss = imp2exp(Rd)'. In terms of programming it's
probably an indication that some further input checking should be added
to the package. In terms of your application, it could be that
something's wrong with your restrictions. (Since 'Rd' seems to be
related internally to the restrictions, I think -- I'm not the author.)
So I suggest to double-check your restrictions. You can also show them
to us.
hth,
