Hi Sven the dependent variable and independent variables are different and X only contained a single indep. variable and y a single dep. variable. So as far as I can see the error message is nonsense. It should be possible to estimate a Bayesian regression  with a single indep variable eg a Bayesian trend function.

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*

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> -- Marcin Błażejowski _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/

My programming expertise only extends to Fortran and Basic-so that will date me!. I have downloaded BACE. zip from Source Forge into my Downloads folder. BACE.zip contains the pdf afticle on BACE and a file BACE.gfn. That is correct: BACE.zip archive contains both: BACE.gfn package and BACE.pdf docs. On my laptop, Gretl resides in C:\Program Files\gretl. I cannot understand what the instruction *pkg install /path/to/BACE.zip *really means . Assuming you put BACE.zip in C: (which gives us a path as C:\BACE.zip) and have gretl already running, do the following steps: 1. Click on 'open gretl console' (third icon at the bottom of main window. 2. type "pkg install C:\BACE.zip" in gretl's console window and press 'Enter'. This just instructs gretl to unzip BACE.zip and put its contains in special place in your user's directory. Why would I install the already downloaded file BACE.zip *i*nto BACE.zip? Basically, because gretl needs to know that such file exists and - that it contains package items. In case of script. The first 3 lines set verbosity, loads bundled dataset and loads BACE package into memory: set verbose off open australia.gdt include BACE.gfn Here you generate time trend and set lags: genr time x_lags = 1 y_lags = 1 Next, you create X list which contains variables with ID's from 6 to 10. Additionaly, you add lags of them + time: list X = 6..10 X = lags(x_lags, X) time Finally, you run BACE for lpau variable as Y, including its lags and all Xs (which corresponds to ARDL(1,1). Const terem may be dropped: BACE(lpau, X, _(with_const=2, Y_AR_p=y_lags)) That's it. Of course, all those things you may do via BACE GUI interface, but some element must be done before (like lagged Xs and time) Marcin -- Marcin Błażejowski _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/

Hi Marcin As advised I downloaded BACE.zip and it installed BACE -infact it appears at th ebottom of the list as a  as a seperate modeling option in the GUI. I then set up a linear TS model with Dep variable (no lags) and a bundle of indep variables (no lags either) including a predefined time trend Sample 1998-2019.  I use the default GUI settings. The result:- _> Options["avg_model_size"] = avg_model_size The symbol 'avg_model_size' is undefined Data error *** error in function BACE_GUI, line 13 > scalar Options["avg_model_size"] = avg_model_size_ There is nowhere in the GUI that one can specify average model size -whatever that might imply. I attach the datafile if it might help identify the problem source. Depvar 2  CATCH_DECL X List VARS   16, 18-21 and 31 Further advice would be welcome. best wishes Brian

Hi Scen so I have now reinstalled the BACE version from the server list -1.2. Same dataset as attached on the previous message

Hi Marcel Thanks for the informationvupdate. Two questions to clarify. Current SVN version? ... should I now re-install the BACE version from the server function list. Did you test it with the dataset I attached? Best Brian

Hi Marcin I may be missing somthing here, but having downloaded BACE.zip from the sourceforge site. The zip file is in Downloads Hence I entered in script ? 'pkg install /Downloads/BACE.zip --local' Invalid option '--local'

Thanks Allin & Marcin problem solved. Brian
