Compute odds ratio (OR)
Returns the odds in each group, and the odds ratio. Takes the cases (n) and total N as a list of two numbers for each of two groups.
oddsratio(grp1 = c(n = 3, N = 10), grp2 = c(n = 1, N = 10), alpha = 0.05)
grp1 |
either odds for group 1, or cases and total N , e.g c(n=3, N=10) |
grp2 |
either odds for group 2, or cases and total N , e.g c(n=1, N=20) |
alpha |
for CI (default = 0.05) |
Returns a list of odds1, odds2, and OR + CI. Has a pretty-printing method so displays as:
Group 1 odds = 0.43
Group 2 odds = 0.11
OR = 3.86 CI95[0.160, 3.64]
List of odds in group 1 and group2, and the resulting OR and CI
