fabtwzCI: FAB t-interval with z-optimal w-function

In fabCI: FAB Confidence Intervals

Description

Computation of a 1-alpha FAB t-interval using the w-function of the optimal FAB z-interval

Usage

fabtwzCI(y, s2, df, muw, t2w, s2w, alpha = 0.05)

Arguments

y	a numeric vector with at least two non-missing values
s2	a variance estimate
df	degrees of freedom corresponding to s2
muw	prior expectation of the mean
t2w	prior variance of the mean
s2w	assumed population variance
alpha	the type I error rate, so 1-alpha is the coverage rate

Details

Internal function for multifabCIhom. It's similar to fabtCI, the difference being that fabtwzCI uses the w-function that leads to the optimal CI if the sampling variance were known.
