Calculate pooled risk difference and its confidence intervals with Mantel-Haenszel's method

Description

Calculate pooled risk difference and its confidence intervals with Mantel-Haenszel's method.

Usage

 RDMH(XTAB, conf.level=0.9) 

Arguments

XTAB

A matrix with 4 columns. The first column is the number of cases in exposed cohort. The second column is the number of cases in unexposed cohort. The third column is the total number of exposed cohort. The forth column is the total number of unexposed cohort. Rows should be composed of different strata or studies.

conf.level

Probability for confidence intervals. Default is 0.9.

Value

estimate

Calculated point estimate of pooled risk difference 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.
