gretl crashed while searching for file within GUI

by Fred Engst

Hi Allin, gretl crashed once again, but for a different reason this time. It seems that whenever I tried to do a search for files within GUI after “file->Open data->User file...” or “file->Session files->Open session…”, it crashes right after it showed a list of files. I can’t remember a time when I did a search like this without gretl crashing. I suspect it has something to do with my character encoding. Even though I use standard English, I have Chinese on my system also. This is more like a FYI, and it is not urgent, as I know how to get around it easily. Attached is the crash report if it helps.

Package KaoTest.gfn to be retired soon

by Sven Schreiber

Dear all, especially those interested in panel cointegration analysis, the KaoTest.gfn package has certain issues and will be removed from the gretl package server soon. The author couldn't be reached to address those issues. The good news is that work is ongoing to start a new package for panel cointegration testing. The plan is that it will offer more tests than the KaoTest package. Nevertheless, if you are a user of that package and need it for your work please keep a local copy of it to be on the safe side. cheers sven

Function package bkw.gfn

by Sven Schreiber

Dear users of collinearity analyses, the function package bkw.gfn by Lee Adkins is going to be retired soon. The reason is that its functionality has been integrated into gretl itself via the new 'bkw' command and 'bkw()' function. See the documentation in gretl 2019b (excellent as always). Please speak up if you need a little transition period. Apart from that, you can of course always keep a local copy of the package for your own use. cheers sven

Re: More minor bugs or errors (Riccardo (Jack) Lucchetti) & (Allin Cottrell)

by Fred Engst

Thanks both Jack & Allin! # 2: now I know why it didn’t work (where I live gretl can’t access the website without a VPN) and have corrected it. #3 & 6: I can live with this. It all has to do with long names. A partial solution is perhaps to add a note field in model icon so that the user can provide a more descriptive information about each model. This will be helpful for someone like me who has a poor memory of the models that I have created and for what purpose, etc. However, this is not a high priority item, just a thought. #5: The sorting issue is only true in the famous mroz dataset that is used by both Wooldridge’s “Introductory Econometrics A Modern Approach" textbook and HIll-Grifit-Lim’s “Principles of Econometrics" textbook. However, I’ve just confirmed, only the one “mroz.gdt" downloaded from Wooldridge’s datalink https://sourceforge.net/projects/gretl/files/datafiles/wooldridge.tar.gz/... <https://sourceforge.net/projects/gretl/files/datafiles/wooldridge.tar.gz/...> seems to have this problem, sorting by wage or lwage have the same results. The one downloaded from POE’s don’t. #7: I can live with this also. I’ll just have to piece multiple models manually. I will try to accumulate more work for you later. :) Thanks again for this great project! Fred

More minor bugs or errors

by Fred Engst

Hi Allin, I love gretl so much, both for my own research and for teaching. I wish I know how to correct the following minor errors on my own, but I don’t, so I’m saving them for you. :) 1) Spelling error in file “csvdata.c” at the very end. When I join a dataset, if there was no change, the returned message is then: "No changes were nade to the dataset”. 2) when I select “help->keyboard shortcut”, an error occurred:”cURL error 56 (Failure when receiving data from the peer)” 3) Once I save and close a model in icon view with a non default name, the next time when I open it, it doesn’t show the model name on the tab. 4) Issue with graphic output from “View->Multiple graphs->X-Y scatters” or “View->Graph specified vars->X-Y scatter” : Font change in graph has no effect after copying it to other apps, such as powerpoint or word. 5) Sorting is not working correctly on some dataset’s variables, such as Mroz dataset’s wage or lwage. Even $hat from regression that I saved on this dataset wouldn’t get sorted correctly either. I have not noticed this issue on other datasets, however. 6) Some models in the Icons view tends to be hidden if I gave long model names. When I try to put some models in "Model table”, this can be a problem. 7) Speaking of Model table, can’t we let it take models with different dependent variables? All we need to do is to list the dependent variable on top of each column. Am I right? 8) Model table’s outputted asterisk is limited to 2, which can be different from the original model’s output. OK, that is all for now. Thanks in advance for all your great work. Fred

Problem opening old Gretl data-file

by Dagfinn Rime

Dear Gretl community, I have a Gretl file, last saved in 2017, that I now can't open. I have updated my Gretl to 2019-build. Error message: First char of varname '_DAY' is bad (first must be alphabetical) a) can I download old version from somewhere? b) is it an easy way to take a Gretl gdt-file and convert it to CSV? Thanks in advance Dagfinn Rime

delete variables

by cruz.echevarria＠ehu.eus

Dear Gretl Community, In the hope that my question is not too silly: Is there a specific command to keep a subset of variables and discard the rest? I have large number of variables in my data set, but I only need a small subset of them. I find that using the "delete" command works, but inefficiently: it would be much easier just so save/keep/maintain/... the small number of variables I am interested in. In other words, is there a complementary command to "delete"? Thanks in advance, Cruz

Dummy

by cruz.echevarria＠ehu.eus

Dear Gretl users, I am aware that the following might be trivial, but I am stuck. Suppose that you have a panel data set whose units are countries identified by a numerical variable, say "ccode". And you want to split the sample into two sub-samples: OECD and non-OECD members. I have tried the following: genr OECD = 0 if ccode == 1 replace OECD = 1 elif ccode == 4 replace OECD = 1 (...) end It does not work. I am aware of the piece of warning in the Hansl's manual for Stata users (page 32). But, does anyone know hos I should do this? Thanks a lot in advance for your cooperation. Cruz

We haven't had that sort of facility in the past, but we do now (it hasn't been much used yet). You can visit the gretl-users page at https://gretlml.univpm.it/hyperkitty/list/gretl-users@gretlml.univpm.it/ click on the topic in question, and vote up or down a reply on that topic. (It seems you have to be logged in to do this; I haven't actually tried it myself yet.) Allin
