Thanks for the report, I see what you mean. This should be fixed shortly, but I want to take a little time to ensure that the fix is robust.

Yes, I think that's right.

I am asking this because I can easily obtain the same results with whighting the model manually, in which case I can also use the White test etc.(and see H0 is rejected). 3)- When I add observations using Data>Add observations, the forecasts window still says "There are no observations available for forecasting out of sample...". (after Cochrane-Orcutt, HL, PW etc.) 4)- When I import a data file with labels, gretl gives the message: "first row label "xxx", last label "zzz" label strings can't be consistent dates" This is not an error message right? Because it sounds like one. I think the "label strings can't be consistent dates" part is unnecessary and confusing. What do you think? 5)- IMO the data menu (along with the variable menu) is really too long. How about considering the following changes to make it look less intimidating: a)- Removing the refresh window item. (I don't know if it is really needed. Besides it doesn't even look like it belongs to the data menu.) b)- Making a default named list called "all variables" and removing the "select all" item. Also, could you provide a means to delete such lists. c)- Having a single entry for compact data and expand data Best regards Talha -- ?An expert is a person who has made all the mistakes that can be made in a very narrow field.? - Niels Bohr (1885-1962) -- ------------------------------ Message: 4 Date: Fri, 20 Jan 2012 16:22:27 +0100 From: Sven Schreiber <svetosch(a)gmx.net&gt; Subject: [Gretl-devel] ldconfig To: gretl-devel(a)lists.wfu.edu Message-ID: <4F1986B3.3070305(a)gmx.net&gt; Content-Type: text/plain; charset=ISO-8859-15; format=flowed Just a small observation: REcently it seems to me that after building gretl from cvs I always have to do 'sudo ldconfig' before I can make gretl start. I don't have hard evidence to support this, though. I'm mostly using Ubuntu 11.10 (and its derivatives like Mint; this observation does not seem to happen just on one machine/platform), maybe something changed from 11.4 to 11.10? cheers, sven ------------------------------ _______________________________________________ Gretl-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel End of Gretl-devel Digest, Vol 60, Issue 7 ******************************************
