stat_EC: Exact-corrected test statistic

In NourHawila/EC: Exact-corrected confidence interval and other useful functions to analyze noninferiority binomial trials

Description

This function calculates the exact-corrected test statistic

Usage

stat_EC(x.T, x.C, N.T, N.C, Delta, delta0)

Arguments

x.T	positive integer representing the observed number of responders in the treatment group
x.C	positive integer representing the observed number of responders in the control group
N.T	positive integer representing the sample size in the treatment group
N.C	positive integer representing the sample size in the control group
Delta	numeric between -1 and 1 representing the constraint for P.C-P.T
delta0	numeric between 0 and 1 representing the noninferiority margin

Value

numeric representing the value of the exact-corrected test statistic

Examples

#First example calculates the exact-corrected test statistic for
#the Rodary et al. (1989) study with proportion of success in the treatment
#group being 83/88 and 69/76 for the control with a 10%
#noninferiority margin.
#Second example calculates the exact-corrected test statistic for
#the Fries et al. (1993) study with proportion of success in the treatment
#group being 8/15 and 3/15 for the control with a 20% noninferiority margin.
