Description

Score method of CI estimation

Usage

1
ciSC(n, alp)

Arguments

n

- Number of trials

alp

- Alpha value (significance level required)

Details

A score test approach based on inverting the test with standard error evaluated at the null hypothesis is due to Wilson for all x = 0, 1, 2 ..n.

Value

A dataframe with

x

- Number of successes (positive samples)

LSC

- Score Lower limit

USC

- Score Upper Limit

LABB

- Score Lower Abberation

UABB

- Score Upper Abberation

ZWI

- Zero Width Interval
