by Artur Tarassow

Dear all, some weeks ago I've started to switch to the sublime editor (https://www.sublimetext.com/) for writing gretl code. Even though I like the simplicity of the gretl editor and its features such as syntax highlighting and auto-itendation, it lacks some features of modern IDEs such as "goto-anything", "goto-definition", custom keybindings, fancy themes, git-implementation, snippets etc. which make life much easier when working on larger projects. Don't get me wrong, the gretl editor is great but was _never_ supposed to become a proper software-development IDE but rather has another focus which is totally fine. So I started to write the "Hansl-Gretl-Language" package for sublime which includes the following features: - 3 gretl build-systems (client mode, batch mode, and REPL mode) for executing hansl code by means of sublime (plots are also working!) - syntax-highlighting - completion of gretl commands, accessors and keywords - some snippet examples for speeding up coding The project still has the following (known) issues: - no auto-itendation (still have to figure out how this works) - issues with some corner-cases which are not syntax-highlighted (regex can become so hard!) The package can be downloaded through sublimes package control system, and can be found here: https://packagecontrol.io/packages/Hansl-Gretl-Language If somebody wants to participate on this project, check out the code on my github repository: https://github.com/atecon/Hansl-Gretl-Language For those interesting in the sublime editor, check out "OdatNurd"'s brilliant tutorials on youtube: https://www.youtube.com/user/nurdz Enjoy the package, Artur

the getQuandl package (and the new name of the Quandl website)

by Sven Schreiber

Hi, we have noticed that the getQuandl contributed function package has stopped working. This package could be used to fetch data series from the Quandl website, but that site was bought by Nasdaq and changed its name. (Nasdaq Data Link, or see data.nasdaq.com) Therefore, the access URLs that the package used are no longer valid. We have contacted the package author, and hopefully the package will be adapted. But in the meantime let me ask, who among the gretl users knew the Quandl data source and/or were using the getQuandl package? Of course we know that the majority of users are not on this mailing list, but still any feedback would be interesting. This may also influence the decision on whether to retire the package in case it were no longer maintained. thanks for any reactions on this sven

gretl 2021d released

by Allin Cottrell

As usual, see http://gretl.sourceforge.net/ This is mostly a bug-fix release, but there are two new features to report: * An enhancement of the "biprobit" command, whereby rho, the correlation between the errors in the two equations, is available as part of the parameter vector, $coeff, and the covariance matrix, $vcv. * Support for linear programming, courtesy of the lpsolve library. On Linux you need to install the lpsolve package to activate this feature (but that's easy via your distro's package manager); in our Windows and macOS packages we supply a suitable build of the library. PDF documentation can be found under the gretl Help menu ("Linear programming"). Here's the change log: 2021-09-30 version 2021d - "biprobit" command: include rho in $coeff, $stderr and $vcv - New function lpsolve(): supports linear programming via the lpsolve library - Prevent opening of general and console preferences dialogs simultaneously - Fix partial breakage of the panel-time plotting facility - Fix potential failure mode in echoing script input lines in the GUI program - Fix a small and somewhat unlikely memory leak - Fix a GUI build error when using GTK 2 - Fix Windows bug: greek-letter identifiers not working in some locales - Fix Mac bug: binary data read/write not accessible - Fix Linux bug: possible crash when running MPI from the GUI program Allin

Estimation of a State Space model with constrained parameters

by Paolo Chirico

Hi, I have to estimate a State Space model where a parameter must have values in a range (between two limit values: L1 and L2) I can't define the derivates (i.e. numeric MLE). Do you have any suggestions? Thank you, Paolo -- Paolo Chirico Università del Piemonte Orientale Dip. di Giurisprudenza e Scienze Politiche, Economiche e Sociali (DIGSPES) Alessandria, Italia

set the panel time dimension details in the GUI?

by Sven Schreiber

Hi, is there a GUI-equivalent of the "setobs" command with the "--panel-time" option? (I don't think so, but maybe I'm missing something.) thanks sven

Is there any way to paste the data when performing a forescasting model?

by José Henriques

I'm working on a college project based on a database of companies in the Iberian Peninsula (SABI). I'm working with data from 30,000 Portuguese companies over a period of 5 years when carrying out the forecasting model with the addition of a temporal unit, I found that I could only enter the data manually. Is there any alternative, during the preparation of the forecasting model that allows pasting the data through excel?

string to epoch

by Riccardo (Jack) Lucchetti

I was playing with the nice COVID international data set available at https://github.com/owid/covid-19-data/tree/master/public/data The csv file contains a "date" column, that gretl reads as a string-valued series. In order to turn it into proper dates, I ended up writing this little function that turns a string valued series holding dates into a numeric string holding the epoch day. The requisite is that the string is organised as year-month-day, with an arbitrary delimiter that must be passed as the optional second parameter to the function (default: dash). <hansl> function series str2epoch(series s, string delimiter[null]) strings datestrs = strvals(s) scalar n = nelem(datestrs) fmt = "%d-%d-%d" if exists(delimiter) fmt = strsub(fmt, "-", delimiter) endif scalar y m d matrix ymd = seq(1,n)' ~ zeros(n, 3) loop i = 1 .. n s_i = datestrs[i] sscanf(s_i, fmt, y, m, d) ymd[i,2:] = {y,m,d} endloop series s_y = replace(s, ymd[,1], ymd[,2]) series s_m = replace(s, ymd[,1], ymd[,3]) series s_d = replace(s, ymd[,1], ymd[,4]) return epochday(s_y, s_m, s_d) end function </hansl> I'm posting it here in case it's useful to someone, but I'd also like to ask you people if you think this as valuable enough to be included in the extra package. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------

stringify() doubt

by Riccardo (Jack) Lucchetti

First, let me give an example of what I'm trying to do: <hansl> nulldata 10 l = defarray("a", "b", "a") x = randgen(i, 1, 3) stringify(x, l) </hansl> does not work, because the label for the string for value 1 is the same as the one for value 3. Fine, I can see the rationale for this. However: imagine I have a cross-sectional dataset of people, where each person has a unique numerical id, but there happen to be two different people whose name is "John Smith". At the moment, we don't seem to have a way to stringify a "name" variable, apart from writing some code for relabelling the first John Smith to "John Smith (1)" and the second one to "John Smith (2)". I don't like this very much. Ideas, anyone? ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
