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

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 -------------------------------------------------------

Multidimensional Poverty Index

by Dhanasekaran Kuppusamy

Hi all Gretl Users, I have written a programme for “Multidimensional Poverty Index“ using Gretl which may be of interest for some one of us and Gretl users. Sample data and script and its results are attached herewith. Dhanasekaran K Title : Multidimensional Poverty Index (MPI) Author : Dhanasekaran Kuppusamy EmailID: Dhanasekaran K<drgkdphd(a)gmail.com> Description: Computes the Multidimensional Poverty Index developed by Alkire and Foster (2011) The Multidimensional Poverty Index (MPI) is a poverty measure developed by OPHI and the United Nations Development Programme for UNDP’s flagship Human Development Reports, and has been published in the reports since then. It reflects the multiple deprivations that poor people face in the areas of education, health, and living standards. This method is flexible and can be used with different dimensions, indicators, weights and cutoffs to create measures specific to different societies and situations.

New package "multiplot"

by Artur Tarassow

Hi all, Sven and I have written a new package which may be of interest for some of you. The "multiplot" package was just released and allows you to create so called multiplots: a single plot file including multiple subplots of various types. Find details here: http://ricardo.ecn.wfu.edu/gretl/cgi-bin/current_fnfiles/multiplot.gfn or check out our github-repo: https://github.com/atecon/multiplot/blob/master/README.md Let us know about eventual bugs. Enjoy, Artur

Speed comparison ARIMA Python Gretl

by Artur Tarassow

Hey all, during the last couple of days I had to use Python's popular 'statsmodels' package for estimating ARIMA type of models. Here is a comparison with gretl's built-in apparatus for those who are interested: https://github.com/atecon/benchmark_arima To summarize: 'In terms of speed, statsmodels is no competitor at all.' ;-) Let me add one thing: The computational heavy task is done in some kalman-function which calls cython code which is written in C. However, tt seems that there optimization algorithm is not well-programmed compared to what Jack and Allin (maybe Sven?) have implemented. Well done, guys! :-) Artur
