Hi, it has often been said that many people do not take gretl seriously as a high-performance research tool. Today Jack posted a file on the sourceforge tracker which runs some comparison benchmarks. I am copying and attaching that file here. (For a successful run you'll need to have R and Octave and Julia installed I believe.) Anyway, I thought that maybe we could jointly put together a gretl working paper that would simply be a collection of speed comparisons (code + result tables). The working title would be "Benchmarking the speed of gretl". I would be willing to coordinate the effort in the sense of testing the codes, as well as putting together and editing (not writing!) the corresponding text snippets. The idea is that everybody who contributes at least one speed comparison between at least two programs (gretl and another) will be a co-author. (But just the code is not enough, the setup and results would have to be explained in a couple of paragraphs, presumably with a result table.) You could start sending the code + explanations immediately. Please mention in the corresponding text snippets which versions of the respective programs you have used and on which machine the benchmark was run; possibly also what method you used to measure the computing time. You can send to the list or to me directly off-list. I cannot promise when that working paper will be ready, as it depends on everybody. I'd say a minimal length would be roughly 10 typeset pages before it would be released. Hope you like the idea and have a good weekend, Sven
