BPmidp.CI: Compute Baptista-Pike midp confidence interval for the odds...

In ORCI: Several confidence intervals for the odds ratio

Description

Compute Baptista-Pike midp confidence interval for the odds ratio of two independent binomial proportions.

Usage

BPmidp.CI(x1, n1, x2, n2, conf = 0.95, interval = c(1e-08, 1e+08))

Arguments

x1	number of events in group 1.
n1	number of trials in group 1.
x2	number of events in group 2.
n2	number of trials in group 2.
conf	confidence level.
interval	solution finding range.
