<> Have you had a look at -h integ- yet? HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von Buzz Burhans Gesendet: Dienstag, 4. Mai 2010 04:58 An: statalist@hsphsun2.harvard.edu Betreff: st: how to find the integral for a portion of a normal distribution. My weak math skills are showing up here - For demonstration purposes, I have generated a set of 100,000 observations with a normal distribution, mean 2.02, SD 1.74 and visualized this data and the portion of observations above 1 with a histogram drawnorm x , means(2.02) sds(1.75) n(100,000) clear hist, xline(1) I also computed the proportion of the observations <=1 from the Z score. What I don't know how to do in Stata is find the integral for the proportions of the distribution above and below 1. How can I determine those two integrals in Stata?
