Should tests of proportions live in ttest?

[cwolock]

Currently proportion tests are part of ttest. On one hand, I understand that proportion tests are also tests of equality of means, so they are related to t-tests in that way (and I believe they are taught at roughly the same time as t-tests, at least in BIOST 511). However, it seems misleading to call them t-tests since they aren't based on the Student's t distribution. There is also an exact option for the proportion test, which doesn't really fit in with t-tests in my opinion. I would be in favor of having proportion tests live in their own function, with both exact and approximate options.

I'm also in favor of having proportion tests live in their own function, for essentially the same reasons as you've mentioned.

I agree!
