Hello Statalist members,
Can someone direct me to a resource (a text or a website) that discusses
exact and approximate confidence intervals for various cases?
For example, when n is large, variance is known, and mu is considered
continuous N(0,1) ... this seems to yield an exact confidence interval using
the z-scale. Other 'cases' mix it up: n is 'small', i.e., less than 30,
distribution is normal, variance known yields an exact confidence interval
using the t-distribution.
Just need to review this. I have several texts but they don't cover this
subject.
Thanks.
Deane
