Re: [Gretl-devel] Correspondence Analysis

This is both an announcement and a plea for help: some time ago, I put together some functions for simple correspondence analysis, which I am not at all an expert of (I used to be pretty good at this stuff in the late 1980s, then I stopped following the literature). These functions are now available as a function package, that you'll find on the server under the "corresp" name. I decided to make this stuff public because it's a nice illustration of how to use string arrays, so you'll need a pretty recent version of gretl to run it. Besides, in order to run the example, you'll also need the datafile attached here, which contains a classic example, used in practically all software implementations as a simple benchmark (see Greenacre (2007), "CORRESPONDENCE ANALYSIS in PRACTICE", Chapman & Hall). The plea for help is: is there anybody out there who will adopt the package? I'm not at all sure I implementend things the right way and, as I said, I haven't followed the literature for a looooong time (and I have no intention/time for doing so). ------------------------------------------------------- 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-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel
