ciCWDx: Continuity corrected Wald method of CI estimation

In RajeswaranV/proportion: Inference on Single Binomial Proportion and Bayesian Computations

Continuity corrected Wald method of CI estimation

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

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)
LCWx	CC-Wald Lower limit
UCWx	CC-Wald Upper Limit
LABB	CC-Wald Lower Abberation
UABB	CC-Wald Upper Abberation
ZWI	Zero Width Interval
