ciCLT: Continuity corrected Logit Wald method of CI estimation

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

Continuity corrected Logit Wald method of CI estimation

Description

Continuity corrected Logit Wald method of CI estimation

Usage

ciCLT(n, alp, c)

Arguments

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

Details

Wald-type interval for the logit transformation of the parameter p using the test statistic (abs(L(phat)-L(p))-c)/SE where c > 0 is a constant for continuity correction and L(y) = log(y/1-y) for all x = 0, 1, 2 ..n. Boundary modifications when x = 0 or x = n using Exact method values.

Value

A dataframe with

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