Description

Continuity corrected Wald method of CI estimation

Usage

ciCWDx(x, n, alp, c)

Arguments

x

- Number of successes

n

- Number of trials

alp

- Alpha value (significance level required)

c

- Continuity correction

Value

A dataframe with

x

Number of successes (positive samples)

LCWx

ZWI

Zero Width Interval

Details

Wald-type interval (for all \(x = 0, 1, 2 ..n\)) using the test statistic \((abs(phat-p)-c)/SE\) where \(c > 0\) is a constant for continuity correction
