I thought i would try this option estimating a simple model (always the best way to gain experience and confidence with the routine).

Independent variable, 1 indep variable  . No lag on Y. . Zero selected for out of sample forecast   Constant -can be omitted.   Best 4 models selected -again as the default.

This was the output:-

Dependent viariable was removed from the X list. It is not there -there is only a single indep variable.
Error message from BACE_GUI():
 Average model size should be greater then 0 and lower than K !!!   Average model size specified is the default 1

Some guidance wlecomed please

Well,

it is strange and IMHO it should not happen, but probably there is a bug.

My suggestion would be to use current development version (which is 1.3 ang can be found here (BACE.zip): https://sourceforge.net/projects/bace-for-gretl/files/snapshot).

Once you download the file just run the followinh line in gretl's script window or console: "pkg install /path/to/BACE.zip". And that's it: you have current SVN version with many bugs fixed and new features added. You my try do run the following HANSL script:

<hansl>
set verbose off
open australia.gdt
include BACE.gfn

genr time

x_lags = 1
y_lags = 1

list X = 6..10
X = lags(x_lags, X) time

BACE(lpau, X, _(with_const=2, Y_AR_p=y_lags))
</hansl>
