In sasLM: 'SAS' Linear Model

Relative Risk of the two groups

Description

Relative Risk between the two groups

Usage

  RR(y1, n1, y2, n2, conf.level=0.95)

Arguments

y1	positive event count of test (the first) group
n1	total count of the test (the first) group
y2	positive event count of control (the second) group
n2	total count of control (the second) group
conf.level	confidence level

Details

It calculates relative risk of the two groups. No continuity correction here. If you need percent scale, multiply the output by 100.

Value

The result is a data.frame.

p1	proportion from the first group
p2	proportion from the second group
RR	relative risk, p1/p2
SElog	standard error of log(RR)
lower	lower confidence limit of RR
upper	upper confidence limit of RR
