lengthTW: Expected length and sum of length of Wald-T method

Description

Expected length and sum of length of Wald-T method

Usage

lengthTW(n, alp, a, b)

Arguments

n

- Number of trials

alp

- Alpha value (significance level required)

a

- Beta parameters for hypo "p"

b

- Beta parameters for hypo "p"

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

Details

Evaluation of approximate method based on a t_approximation of the standardized point estimator using sum of length of the \(n + 1\) intervals
