RE: Confidence intervals for Emax model

From:"Hu, Chuanpu" Subject:RE: [NMusers] Confidence intervals for Emax model Date:Fri, March 1, 2002 9:04 am Dear Daren, Just my 2 cents. To compute something that is not analytically available, I suppose nothing more exact can be done if you can "simulate away." If one variability of eta1 and eps1 dominates the other, your U95% and L95% should do. If not, you might want to use 2.24 instead of 1.96 to be conservative.
