Dear GRETL folk, greetings from Paris ! I am still on my demand system analysis and AIDS modelling.
This project involves regressions in on large cross-sections (~ 10 000 observations) on households. Meanwhile, to control for heterogeneity, I use numerous lists of qualitative variables, each on different themes like: household composition education profession housing attributes location in the hexagon ... etc. those lists are often composed of contiguous variables names, as for example: x1 x2 x3 x4 x5 As often in such work one likes to account for lots of attributes, so one needs to create long lists. In a famous paper by Blundell, Pashardes and Weber, 1993, there are around 150 such variables. My problem is that I cant find in the doc a way to call / create lists with contiguous variables without enumerating all the variables names. So, is it possible to call a list with something like: list housing = x1 to x5 x13 instead of: list housing = x1 x2 x3 x4 x5 x13 thanks for any advice ! cheers Franck -- Franck Nadaud CIRED UMR 8568 CNRS - EHESS, ENPC, ENGREF, CIRAD 45 bis avenue de la Belle Gabrielle 94736 Nogent-sur-Marne Cedex TEL: 33-1-43-94-73-94 FAX: 33-1-43-94-73-70 MOB: 06-07-39-92-75 France
