Miettinen-Nurminen Score Test Statistic for Two-Sample Risk Ratio
Description
Obtains the Miettinen-Nurminen score test statistic for
two-sample risk ratio possibly with stratification.
Usage
zstatRiskRatio(n1, y1, n2, y2, riskRatioH0 = 1)
Arguments
n1
The sample size for the active treatment group.
y1
The number of responses for the active treatment group.
n2
The sample size for the control group.
y2
The number of responses for the control group.
riskRatioH0
The risk ratio under the null hypothesis.
Defaults to 1.
Details
The Mantel-Haenszel sample size weights are used for stratified
samples.
Value
The value of the score test statistic.
