I'm trying to evaluate my forecasts using "fcstats()", but the results are not quite good. Could you please take a look at my script?
<script>
open australia.gdt
smpl ; 1989:4
Modelo <- ols E const PAU PUS --robust
fcast 1972:1 1991:1 E_hat
smpl full
matrix Avaliacao = fcstats(E, E_hat)
</script>
Is there anything wrong in it?
I think I've got some new information about the problem. Please take a look at the matrices ("Avaliacao") I've built using Gretl 1.9.2 and Gretl 1.9.3cvs:

Conclusion: the same script produces different results on each Gretl version.
Best,
