Nick in original paper they call it decile plot, because they had enough data, and the variable was continuous, which would make it possible to create deciles. In my case, I simply ran estat gof , group(10) table outsample which created a table like this: Group Prob Obs_1 Exp_1 Obs_0 Exp_0 Total -------+--------+-------+--------+--------+----------+-------- 2 0.0012 290 306.2 259754 259737.8 260044 4 0.0063 1821 1844.7 294979 294955.3 296800 7 0.0127 4293 4297.6 335630 335625.4 339923 9 0.0221 7164 7113.7 324602 324652.3 331766 10 0.0371 1776 1781.4 46259 46253.6 48035 then i draw a scatter plot with Prob on X-axis, then Obs_1/Total on Y-axis. I had only 5 groups instead of 10 deciles. cheers On Thu, Jul 7, 2011 at 6:48 AM, Nick Cox <n.j.cox@durham.ac.uk> wrote: > As I understand it, you don't need to create deciles at all for your problem.
