Hi:

I apologize for posting in the R listserv. But I am trying to do the
following in R.
I am trying to construct Bivariate 95% Approximate Confidence interval for
the mean vector p=(p1,p2) similar to what we have in the univariate case.

[image: \hat p \pm z_{1 - \frac{1}{2}\alpha} \sqrt{\frac{1}{n}\hat p
\left(1 - \hat p \right)}]



Should I be using bivariate tolerance region instead? Any thoughts?

Thanks
Anamika
