In yelleKneK/SMSD: Sequential Methods for Study Design

ProbGn

Description

This function replicates the ProbGn function from chapter 2. This program computes the probability of K(n) > c*sigma for given alpha and sample size.

Usage

prob_gn(alpha, n, c_min = 0, c_max = 10, by = 0.04, dec = 4)

Arguments

alpha	The selected significance level.
n	The selected sample size.
c_min	The minimum value of c to try in the calulcations, default = 0.
c_max	The maximum value of c to try in the calculations, default = 10.
by	The increment of the sequence between c_min and c_max, default = 0.04.
dec	The number of decimal places to use when removing probabilities of 0 and 1 from the ends of the results.

Value

A sequence of values of c and the corresponding calculated probabilities.
