Gretl & online teaching

Like Sven mentioned, conference programs like Meet, Teams and Skype have the option of sharing the "desktop", which sends to the audience the entire screen of the lecturer as seen by him/her (at least in Window, do not know about Mac OS) bye Stefano -- ________________________________________________________ Le informazioni contenute in questo messaggio di posta elettronica sono strettamente riservate e indirizzate esclusivamente al destinatario.

Hamilton trend-cycle decomposition

by Riccardo (Jack) Lucchetti

Hi all, yesterday, after having taught my students the HP decomposition, I wondered if I should also tell them that one of the greatest time-series econometricians on Earth recently wrote a rather scathing paper entitled "Why You Should Never Use the Hodrick-Prescott Filter", where he proposes a simple alternative. So this morning I rustled up a little script with Hamilton's filter. Here it is: <hansl> function series hamcycle(series y, bool do_plot[1], string title[null]) h0 = 2 * $pd h1 = h0 + 4 list PROJ = y(-h0 to -h1) ols y 0 PROJ -q # ht = $yhat hc = $uhat if do_plot if !exists(title) title = argname(y) endif print title diff8 = y - y(-h0) setinfo diff8 --graph-name="Random walk" setinfo hc --graph-name="Regression" list PLT = diff8 hc plot PLT options time-series with-lines literal set linetype 1 lc rgb "#ff0000" literal set linetype 2 lc rgb "#000000" literal set key top right printf "set title '%s'", title end plot --output=display endif return hc end function # example nulldata 300 setobs 4 1947:1 open fedstl.bin data gdpc1 expgsc1 pcecc96 list Y = gdpc1 expgsc1 pcecc96 LY = logs(Y) strings Titles = strsplit("GDP Exports Consumption") k = 1 # reproduce part of figure 6 loop foreach i LY --quiet hc = hamcycle($i*100,,Titles[k++]) endloop </hansl> Should we turn this into a function 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 -------------------------------------------------------

Gretl-Hansl "IDE" for Sublime editor

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

gretl 2020c released

by Allin Cottrell

As usual, see http://gretl.sourceforge.net/ A couple of notes: (1) The 32-bit Windows installer now has "32" in its name: gretl_install-32.exe (and it's no longer the default download for Windows, that's now the 64-bit version). (2) We're no longer updating the legacy OS X builds (for 32-bit Intel and PPC, both requiring X11/Xorg). 2020b was the last gretl release for those platforms. The 64-bit "quartz" build of gretl will run on macOS 10.6 or higher. Here's the change log: 2020-07-31 version 2020c - New feature: thematic maps, supported by new "geoplot" addon; allow loading GeoJSON and ESRI shapefiles as gretl datasets - New feature: offer a choice of plotting styles or themes, via GUI and also via a new "set" variable, graph_theme; plus set the default to the "dark2" theme - Add new bincoeff() function, giving binomial coefficients - Add new sgn() function: returns the sign of its argument - Improve error message in case of invalid gnuplot path - loop: make "quiet" operation the default - Path-searching for inputs: improve the mechanism for storing likely locations based on the opening of scripts - Packaged datasets: show type and size in the GUI, as well as a brief description - GUI data access: add convenience menu items for accessing files supplied by "addons" such as SVAR - bwrite() and bread() functions: support JSON as well as XML for representing gretl bundles - atof() function: allow giving a string-valued series as argument - strlen() function: generalize to allow strings array and string-valued series arguments - pshrink() function: add an optional argument to avoid skipping missing values - mshape() function: make the third argument optional and document the new behavior - Fix bug: failure of negative matrix index (exclusion) when a value of -999 was given - Fix bug: the "restrict" command as applied to VECMs could emit an unwanted newline even given the --silent option - Fix bug: "panel plot" coud crash under certain conditions - Fix bug: ensure greater precision when printing values to 15 or more significant digits - Fix bug: possible error in Spearman's rho for the case of no ties - "fractint" and "hurst" commands: make the estimated fractional difference or exponent accessible via the $result accessor - "xtab" command: fix for the case when one or more of the series to be cross-tabulated are string-valued - "summary" command: don't provide spurious results for string-values series - "scatters" command, time-series variant: try harder to get appropriate time-axis tics - "pkg" command: enable variant "pkg index addons" to update the index of installed "addon" packages - "set" command, "initvals" keyword: clarify the status of this setting (non-persistent) - String-valued series: drop any unused strings when sub- sampling with the --permanent flag, and when saving a sub-sampled dataset via the "store" command - Arrays of strings: support union and intersection via the "||" and "&&" operators respectively - Error reporting: be more specific when the problem is an out-of-bounds index value - Datasets supplied with gretl: include a version of R's "swisspharma" data; enhance the grunfeld panel dataset - User's Guide: incorporate the previously stand-alone MIDAS documentation as two new Guide chapters - MS Windows and macOS builds: update to gnuplot 5.2.6 - macOS: provide 64-bit builds of x13as and tramo-seats - Building gretl on MS Windows: updates and improvements to the auto-generated support files - Update several translations - Numerous small bug-fixes -- Allin Cottrell Department of Economics Wake Forest University

How to undo an action in Gretl?

by Cristián Arturo Ducoing Ruiz

Hello Gretl friends, In two weeks I'll begin to teach the course "Economic History: Booms and Busts - Skills for Understanding Crises" This online course was designed to teach economic history through statistics and the software chosen, of course, it's Gretl! The initial level of the students is quite basic, and one of the problems we have detected is the great majority of them don't have any experience with statistical software beyond Excel. So, they are used to *undoing* actions if they make a mistake. *The question. *As I usually work in gretl with *Hansl* instead of the GUI, I haven't realized that there is not an "undo" button in the GUI... *Is there a way to undo an action in Gretl?* Example, if I delete a series, could I undo this action? if the answer is yes, how? Thank you in advance and I'll keep you updated regarding the reception of the course. Best and happy weekend -- Atte. Cristián Arturo Ducoing Ruiz
