I'm studying published journal articles on my topic, and I'd like to reproduce their analysis. How can I get a copy of their dataset and enough specifications to reproduce their numerical results?
In my specific case, I'm studying Stecklov et al. (2005), published in Demography, and they're using PROGRESA datasets which are publicly available, but when I try to reproduce their results, all the base statistics are off by a bit, and the regressions come out a bit different. Probably I'm just including or excluding a few different cases, but what can I do to identify the difference?
