Create a dummy

by Periklis Gogas

I am working on oil prices "WTI" Is it possible to create within Gretl a dummy that takes the value 1 when WTI goes up and 0 when WTI goes down? For example within Excel for a column A that contains WTI it is something like IF(A2>A1,1,0).

Session objects not saved

by Marcelo Duarte

Dear professors, I'm using gretl2019a_git on windows 7 (64bit). I usually save sessions with models to keep track of all the regressions made. I have 1 session saved with 10 OLS regressions and everything is ok. I also have another session with 10 Fixed Effects regressions, which, when opening such session, gives me the following error: "10 session object(s) could not be rebuilt" I've also tried to save OLS and FE regressions in the same session and it rebuilds OLS' but not FE's. The same problem occurred with gretl2018d. Hope you can help me. Thanks, Marcelo

Re: [Gretl-users] Gretl-users Digest, Vol 144, Issue 18

Date: Wed, 23 Jan 2019 14:31:25 +0100 From: Sven Schreiber <svetosch(a)gmx.net> > Apart from waiting for a bugfix I can only advise a workaround: Restart > gretl and use the command log that gretl records automatically and save > that as a script. (In the Tools menu.) There you will see the data file > you loaded ('open') and you will see your FE estimation command > ('panel'). When you re-run that script you should get your results back. The workaround worked very well. Date: Wed, 23 Jan 2019 08:57:13 -0500 (EST) From: Allin Cottrell <cottrell(a)wfu.edu> > Problem found: it's due to the weird way that the Windows C library > writes nans (Not a Number). A fix will be forthcoming shortly. Thank you both very much. Marcelo

ISSUE: Figure's style changes when altering its size

by Artur T.

Dear all, since some time I observe that a figures' style changes when using the 'Bigger' or 'Smaller' buttons below the figure when calling it using the "--output=display" option. This affects line-colours as well as line-width. This happens on linux (and I think also Windows). Note, that I observe this behaviour at least since half a year. Today I've used current git and gnuplot 5.2 patchlevel 2. <hansl> open AWM18.gdt -q list L = YER PCD plot L options time-series with-lines literal set linetype 1 lc rgb "black" lw 3.5 literal set linetype 2 lc rgb "orange" lw 2.5 literal set key top right end plot --output=display </hansl> Best, Artur

Maximum likelihood forecasting

by Olasehinde Timmy

Dear Professors, I will like to know how to compute a dynamic forecast from maximum likelihood estimation. For example, If I estimated a ad-hoc GARCH model as follows series e=inf - beta1-beta2*inf(-1) series h=var(e) series h=alpha+theta*e(-1)^n So how would I forecast dynamically variable "inf" and "h". I would appreciate if you can share a loop code for this. Thanks Timmy J.O
