The Wald confidence interval for the binomial probability

Source: R/Wald_CI_1x2.R

Described in Chapter 2 "The 1x2 Table and the Binomial Distribution"

Wald_CI_1x2(X, n, alpha = 0.05)

Arguments

X

the number of successes

n

the total number of observations

alpha

the nominal level, e.g. 0.05 for 95% CIs

Value

An object of the contingencytables_result class, basically a subclass of base::list(). Use the utils::str() function to see the specific elements returned.

Examples
