Obtains the Miettinen-Nurminen score test statistic for
two-sample rate ratio possibly with stratification.
Usage
zstatRateRatio(t1, y1, t2, y2, rateRatioH0 = 1)
Arguments
- t1
The exposure for the active treatment group.
- y1
The number of events for the active treatment group.
- t2
The exposure for the control group.
- y2
The number of events for the control group.
- rateRatioH0
The rate ratio under the null hypothesis.
Defaults to 1.
Value
The value of the score test statistic.
Details
The Mantel-Haenszel weights are used for stratified samples.
Examples
zstatRateRatio(t1 = c(10, 10), y1 = c(4, 3),
t2 = c(20, 10), y2 = c(2, 0), rateRatioH0 = 1)
