RE: st: how to find the integral for a portion of a normal distribution. |

Doesn't your suggestion fit only if the curve is standard normal?, i.e. mean 0, SD 1? Perhaps my use of integral is incorrect; what I want is the area under the curve of a normal distribution, mean 2.05, sd 1.75 for the portion >= threshold =1, and then the portion < 1 Buzz statalist@hsphsun2.harvard.edu] On Behalf Of Hollis,Michael E Sent: Monday, May 03, 2010 9:36 PM To: statalist@hsphsun2.harvard.edu Subject: Re: st: how to find the integral for a portion of a normal distribution. I may be missing something here, but can't you simply use the normal distribution with mean=proportion z >= some threshold, q=1-p and variance p(1-p)/n? No integration involved. As I said, I might be missing something!
