 oddsratio R Documentation

Compute odds ratio (OR)

Description

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.

Usage

``````oddsratio(grp1 = c(n = 3, N = 10), grp2 = c(n = 1, N = 10), alpha = 0.05)
``````

Arguments

 `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)

Details

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]
```

Value

• List of odds in group 1 and group2, and the resulting OR and CI

oddsratio(grp1 = c(3, 10), grp2 = c(1, 10), alpha = .01)
