ciCWD: Continuity corrected Wald method of CI estimation

In proportion: Inference on Single Binomial Proportion and Bayesian Computations

Description

Continuity corrected Wald method of CI estimation

Usage

ciCWD(n, alp, c)

Arguments

n	- Number of trials
alp	- Alpha value (significance level required)
c	- Continuity correction

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

Value

A dataframe with

x	Number of successes (positive samples)
LCW	Wald Lower limit
UCW	Wald Upper Limit
LABB	Wald Lower Abberation
UABB	Wald Upper Abberation
ZWI	Zero Width Interval
