Description

Expected length and sum of length of Exact method

Usage

1
lengthEX(n, alp, e, a, b)

Arguments

n

- Number of trials

alp

- Alpha value (significance level required)

e

- Exact method indicator in [0, 1] 1: Clopper Pearson, 0.5: Mid P The input can also be a range of values between 0 and 1.

a

- Beta parameters for hypo "p"

b

- Beta parameters for hypo "p"

Details

Evaluation of Confidence interval for p based on inverting equal-tailed binomial tests with null hypothesis H0: p = p0 using sum of length of the n + 1 intervals.

Value

A dataframe with

sumLen

The sum of the expected length

explMean

The mean of the expected length

explSD

The Standard Deviation of the expected length

explMax

The max of the expected length

explLL

The Lower limit of the expected length calculated using mean - SD

explUL

The Upper limit of the expected length calculated using mean + SD
