IRRMH: Calculate pooled incidence rate ratio and its confidence intervals
with Mantel-Haenszel's method
Description
Calculate pooled incidence rate ratio and its confidence intervals
with Mantel-Haenszel's method.
Usage
IRRMH(XTAB, conf.level=0.9)
Value
estimate
Calculated point estimate of pooled incidence rate ratio with Manterl-Haenszel's method.
conf.int
A numeric vector of length 2 to give upper/lower limit of confidence intervals.
conf.level
Simply return the value of given conf.level.
Arguments
XTAB
A matrix with 4 columns.
The first column is the incidence in the exposed cohort.
The second column is the incidence in the unexposed cohort.
The third column is the observed person-time of exposed cohort.
The forth column is the observed person-time of unexposed cohort.
Rows should be composed of different strata or studies.
conf.level
Probability for confidence intervals. Default is 0.9.
