by Allin Cottrell

Apologies for cross-posting, but here's the change log for the 2021c release, now available at http://gretl.sourceforge.net/ 2021-08-30 version 2021c - New function contains(): indicates whether a numerical object contains members of a specified set - New function bcheck(): aids in handling bundle arguments to user-defined functions - New command "panspec": substantially, the old "hausman" command under a different name; for the moment, "hausman" is still kept as an alias for backward compatibility - fcstats() matrix row labels: distinguish U1 vs U2 variant of Theil's U statistic - msplitby(): allow for more flexible syntax - printing of bundles: sort members by type and key - "print" command: make more flexible, it now includes most of the functionality of "eval" - "var" command with --lagselect option: add a --minlag option to allow testing against 0 lags, or imposing the assumption that at least p > 1 lags are needed - "set" command: new variable "datacols" to control the max number of series to print side by side - "foreign" command mechanism: updates to support version 4.1.0 of R and version 8.0 of Ox Console - "eval" command: introduce "=" as an alias - extend the ".=" operator to the "strings .= string" case - GUI: introduce experimental features: plot collections and integrated console - GUI: add option to use the tab key as the trigger for autocompletion in the script editor and console - GUI: add command-line options: --new to start a new gretl instance unconditionally and --single to use a single program instance unconditionally - GUI script editor: make the Find box appear at the foot of the window, not in a separate dialog - GUI: provide larger (24 pixel) toolbar icons for use on small, high-density displays in particular - GUI: numerous other small fixes and enhancements - MS Windows, 64-bit: update to gnuplot 5.4.1, patched to avoid too-big fonts on Windows with Ultra HD display - Fix bug: spurious results from "system" command in case of exact collinearity - Fix bug: spurious reduction of the sample range in the grid variant of "panplot" with some patterns of missing values - Fix bug: wrong results from the polyfit() function when applied to panel data - Numerous additional small bug fixes - Internals: make "libset" code more compact and efficient - Internals: clear out old gettext variants that encoded translations in a Windows code page rather than UTF-8 - gretl_bundle.h: rename argument named "template" to avoid trouble with C++ - Substantial enhancements to the SVAR and regls addons - New "logging" addon - New, substantially updated Russian translation - Cleanup: remove the "arbond" command, in favor of "dpanel", and add some dpanel enhancements -- Allin Cottrell Department of Economics Wake Forest University, NC

gretl 2021c for M1 Mac

by Allin Cottrell

Hello all, We've just realized there's a problem with the gretl 2021c package for M1 Macs: the gnuplot executable has some incorrect library links, meaning that it won't start -- so gretl can't create any plots. This is fixed in a new package uploaded earlier today. If you happen to know of anyone who downloaded the broken M1 package, please pass on the word that there's now a fix. One point to add: the fixed package now on sourceforge is not "notarized", so to install it you'll have to bypass Apple security, as explained at http://gretl.sourceforge.net/osx.html By tomorrow there will be a notarized version of the fixed package in place.

The 2021c release candidate is available (with apologies for cross-posting)

by Riccardo (Jack) Lucchetti

Hi all, on behalf of the development team, I'm glad to announce that we're about to release gretl 2021c. The official release will take place in a week or so, but you can already see what's new by downloading and installing the 2021c release candidate: 64-bit Windows: https://sourceforge.net/projects/gretl/files/snapshots/gretl_install-64.e... Mac OS (Intel): https://sourceforge.net/projects/gretl/files/snapshots/gretl-macos-intel.... Mac OS (M1): https://sourceforge.net/projects/gretl/files/snapshots/gretl-macos-arm64.... To have a quick idea of what the new stuff is, take look at the Changelog: http://gretl.sourceforge.net/ChangeLog.html In fact, we'd appreciate it very much if you could give these versions a good go: we have tried to squash all the bugs we were aware of, but you can never be 100% sure, so please hammer on the release candidates as much as you can. Some of the new GUI features are somewhat experimental, so we'd be grateful if you could try them out. To enable them, go to Tools>Preferences>General and look for the following: 1) the "plot collection" feature (multiple plots in one window); see the help for "set plot_collection" 2) the "Main window includes console" feature (try it for yourselves, I don't want to spoil it for you). Between now and the official release, we'll only fix any bugs you may report (no new features), and give the translators some time to send us updates of the PO files. As of now, the only localisations that are 100% complete are Italian and Russian (thanks to Olesya Petrenko). Should you have any question or comment, please feel free to contact any of us. Thanks! PS: Linux people will have to download the source and compile it themselves; the source code is at https://sourceforge.net/projects/gretl/files/snapshots/gretl-source.tar.x... If you need guidance on how to build, have a look at Appendix B in the User's Guide, or watch the excellent video by Clive Nicholas: https://youtu.be/WSdZkd-uln4 ------------------------------------------------------- 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 -------------------------------------------------------

why cmod?

by Sven Schreiber

Hi, I'm wondering why the cmod() function is needed. It computes the modulus of a complex number (or many of them in a matrix), OK fine. But so does abs(). And abs() also works on plain real numbers, where cmod cannot be used. Could it be a path-dependent thing: first abs() didn't cover complex numbers but then rendered cmod() obsolete by also working on those? Or is there anything else which I'm missing? Otherwise, maybe a case for deprecating or hiding cmod? thanks sven

Retrieving the predicted value series from an ARMA model

by Brian Revell

While the forecast GUI option with OLS and ARIMA provides a printable table of actual, fitted and residual, I can see no way of retrieving and adding the fitted/residuals as seperate series in the data file from the Analysis option. As it is often the case that the dependent variable series is a transformation of another original data series (eg log), it would be helpful if the fitted series displayed in log values could be retrieved to preclude the necessity for creating a new variable and manually entering the data for subsequent reconversion to the original unlogged fitted values. Perhaps there is an option to do this but I cannot see where it might be.
