Hi, because of Corona a lot of teaching is switching to online distance formats. I am not yet directly affected, but thinking about the future I was wondering what options exist. Please share your ideas and experiences. - Skype: (Only) the whole screen can be shared AFAIK; so this would work in principle. Doing this with many participants may not be so great, but I guess everybody can judge for themselves. - Zoom: is it true that only a certain application window can be chosen to be shared? I like that approach, but for gretl with its many windows it would be a problem. - Go-to-Meeting: similar problem as with Zoom, I think (but would need to re-check). A workaround for the many-gretl-windows problem may be to run a version of gretl with GTK3 and use the "broadway" technology to redirect the gretl interface into a single browser window (locally), which could then be shared in the videoconference. (The build with GTK3 is standard on modern Linux distros, but the official Windows version is with GTK2.) Any other ideas? thanks sven

gretl 2020b released

by Allin Cottrell

See http://gretl.sourceforge.net/ as usual. The main point of this release (not so long after 2020a) is to provide a package that should work better with macOS 10.15 "Catalina". But there are benefits from updating on other platforms too. 2020-04-11 version 2020b - Update gretl copyright notice - Revise macOS build: don't require initialization via shell script, and link against version 10.9 of the SDK - "gnuplot" and "plot" commands: add a --ylogscale option - "store" command: add --matrix option to save a matrix in the form of a dataset - strvals(): support retrieval of subset of string values for current sample range - ODBC importation: correct the handling of string-valued series; add --verbose and --no-align options; ensure appropriate error messages in GUI usage - "dataset addobs": add a --panel-time option - "slicing" of arrays: allow use of selection vector - Functions called via "if": show any printed output - "dataset addobs": add --panel-time option to extend a panel dataset in the time dimension - stack() function (see Guide chap. 4): replace option flags with optional arguments - monthlen(): allow for series arguments - Revise handling of string-valued data in exportation to Stata .dta format - Hide the recently added funcerr() function and replace it with the new function errorif() - Streamline building of "online" help files - Fix for normalization of paths on MS Windows - Several minor bug-fixes -- Allin Cottrell Department of Economics Wake Forest University

covid-19 data via dbnomics

by Allin Cottrell

Hello all, In case anyone hasn't noticed: covid-19 data for many countries, and regions within some countries, is now available via dbnomics (which means within gretl too). See https://forum.db.nomics.world/t/covid-19-daily-data-from-csse-at-john-hop... In the gretl GUI, you can go to /File/Databases/DB.NOMICS/Browse and then, in the "DB.NOMICS providers" window, select "JHU" (Johns Hopkins University) to get three databases: "Confirmed cases", "deaths" and "recovered". Each database contains many per-country and per-region daily series. Allin

Re: online teaching with gretl

by Fritsche, Prof. Dr. Ulrich

Synchronous online teaching is demanding. If you consider asynchronous teaching you can simply videotape the screen (possibly including yourself via the laptop camera) and audio using Open Broadcaster Software (OBS Studio) and upload the video. Q&A sessions can afterwards be realized using chat rooms or open meeting rooms (we use OpenOLAT in Hamburg). To be honest, I have not yet used synchronous online teaching only videotaped screens with tutorials using OBS. Some ideas for alternatives to Skype and Microsoft Teams and the sharing solutions therein (not sufficiently tested): Jitsi meet with the respective Chrome extension: no accounts, anonymous, open source, encryption. I used it only for conference calls but it seems to be very simple Slack Whereby Maybe it helps a bit. Beste Grüße, U. F. > Am 28.03.2020 um 14:38 schrieb Sven Schreiber <svetosch(a)gmx.net>: >

online teaching

by Stefano Fachin

slightly OT, but possibly useful: an interesing opensource whiteboard for Linux, Windows, MacOS question: has any of you used an android tablet as a graphic board (possibly attaching it the pc via USB port)? bye Stefano -- _________________________________________________________________________ Stefano Fachin Professore Ordinario di Statistica Economica Dip. di Scienze Statistiche Università di Roma "La Sapienza" P.le A.

Import data from ECDC for corona virus

by F.R.Costa

Hi guys, I hope this email finds you all well. We're living really tough times, unfortunately! I was looking into the data for corona virus from ECDC (European Agency for Disease Prevention and Control) and trying to import it correctly into gretl in simple steps. I'm sure this is easy but I'm not seeing the way to do it. Maybe someone can give me some help. Here is the data link: https://www.ecdc.europa.eu/sites/default/files/documents/COVID-19-geograp... Or, alternatively, you can go to https://www.ecdc.europa.eu/en/publications-data/download-todays-data-geog... and just download the latest figures. What's the best way to import this into Gretl? Best wishes to all and keep safe! F.R.Costa -- Securely sent with Tutanota. Get your own encrypted, ad-free mailbox: https://tutanota.com
