[R] Non : Confidence intervals for p**2 ??
Dear List, I was asked to calculate a confidence interval for p*p. Is there any standard techniques for calculating such an interval? Delta Method? Thank you in advance!

Thank you in advance! Cheers, Patrik If p is meant to denote a probability between 0 and 1, then pL^2 p^2 pU^2 is exactly equivalent to pL p pU where pL and pU are the upper and lower limits for p. Indeed, this will be so if p is any quantity which is necessarily non-negative. Hence, if this is your situation, simply square the confidence limits for p. If, however, this is not your situation, then please explain what p represents. Best wishes, Ted.

Thank you in advance! if p is a generic value (i.e. not a probability) and you know the variance (and are willing to assume normality) then you can indeed use the delta method; there are a variety of other techniques if you have the original data: fitting profile confidence limits, various resampling methods including bootstrapping, etc. (See section 6 of chapter 7 at http://www.zoo.ufl.edu/emdbook for more details if you like).
