These functions convert between probabilities and odds ratios. p_to_OR calculates the odds ratio given two probabilities, while OR_to_p2 and OR_to_p1 calculate the second and first probability, respectively, given the other probability and the odds ratio.
Usage
p_to_OR(p1, p2)
OR_to_p2(p1, OR)
OR_to_p1(p2, OR)
Arguments
- p1
The first probability.
- p2
The second probability.
- OR
The odds ratio.
Value
p_to_OR: The odds ratio corresponding to the given probabilities.
OR_to_p2: The second probability corresponding to the given first probability and odds ratio.
OR_to_p1: The first probability corresponding to the given second probability and odds ratio.
Examples
p_to_OR(0.4, 0.6)
#> [1] 2.25
OR_to_p2(0.4, 2.25)
#> [1] 0.6
OR_to_p1(0.6, 2.25)
#> [1] 0.4
