Up till now, gretl has supported only three-stage least squares for
estimating systems of simultaneous equations. Now, in CVS and in
the win32 snapshot available from sourceforge, I have added support
for FIML and LIML (along with automatic testing of over-identifying
restrictions). I have also added the Hansen-Sargan test for
over-identifying restrictions, for 3SLS and SUR.
I'm looking for help in testing these new additions. I can
replicate the benchmark results for that workhorse, Klein's "Model
1", but I'm finding it hard to find other benchmarks to test
against. So if anyone has datasets on which they've estimated
equation systems using FIML or LIML with other programs, I'd be very
grateful if you could either:
* See if you can replicate the results using gretl, and let me know
what happens; or
* Send me a copy of the dataset and the output from the other
program, so I can try the replication.
Thanks very much for any assistance.
