Dear all: Does it provide Box-Pierce Q statistic to test if residual is autocorrelation for ARIMA in gretl ? Thanks a lot

Graph

by Daniela Tatiane Santos

Dear, I would like to know how can I plot a graph in panel. I would like to plot the dependent and independent variables, after obtaining the results of a fixed effects model. I was only able to plot the results for the error, not to the variables estimated in the x and y axis. After obtaining the results in gretl, could I plot the results on excel? I thought this was a solution because I can not do the graphics panel in gretl. Cordially, Daniela Tatiane dos Santos

Perhaps the algorithm just failed to converge. > Could you send your data so that I can replicate your problem? I would go further than Jack, and say that non-convergence of gretl's ARIMA routine is quite unlikely to be a bug, and probably reflects a misspecified model. But if we can see your data and model we can check that. As for the incomplete clearing of the model specification dialog, yes, that is a bug (or absence of expected feature). It's now fixed in CVS.

Bugs in ARIMA

by Bülent Miran

Dear Allin, During my ARIMA modellings, I encountered several bugs. For example when I got a trial with certain p and q parameters, I couldn't find the ARIMA estimation with those parameters. Sometimes I used the clear button to clean the previous model's parameters, but the new ARIMA estimation was presented with previous model's parameters.

gretl error: Error retrieving data from server

by Artur Tarassow

Dear gretl community, Since a week I am not able to retrieve functions from the server. The error message which I obtain is: "Error retrieving data from server" Are there any problems with the server or is there a more serious problem with gretl (current cvs on Ubuntu 11.04)? Best, Artur

Gretl Wiki

by Henrique Andrade

Dear Gretl Community, I think we have a problem in Gretl Wiki (http://gretlwiki.econ.univpm.it). Someone (a spammer?) is inserting links on the page that aren't related to Gretl: http://www.vivwestwood.uk.com/ http://www.thediamondtrade.com/ http://www.outdoorfountains.com/ This is the second time I see that problem. In the first ocasion I deleted the spam-lines but I think this is not working.

exporting data via odbc

by RENIER Mélanie

Dear all, I am currently using Gretl with Oracle. I retrieve data from the server to gretl via an SQL, then I make predictions in gretl. I would like to know if it is possible to next export the database with the prediction results directly on the server? Such as other users have access to the new database. If yes, how to achieve this? Thanks in advance, Kind regards, Mélanie

I notice that R and Stata do it the same way as X-12-ARIMA and gretl (i.e. they count the variance among the parameters when computing the information criteria). Allin Cottrell
