oddsRatio: Odds Ratio for Multiple Contigency Tables

In MaayanLab/genesetr: Manipulate, Test, and Visualize Gene Set Overlaps

Description

Computes a vector of odds ratios given a set of contingency tables.

Usage

oddsRatio(a, b, c, d)

Arguments

a	A vector of values where a_i corresponds to t_i
b	A vector of values where b_i corresponds to t_i
c	A vector of values where c_i corresponds to t_i
d	A vector of values where d_i corresponds to t_i

Details

Given a set of contingency tables T, where T = {t_1,t_2,...,t_n-1,t_n}, with each t_i of the form:

	setA		¬setA
setB	a		b	|	a + b
¬setB	c		d	|	c + d
	a + c		b + d	|	a + b + c + d

return a vector of odds ratios R=r_1, r_2,...,r_n-1,r_n where r_i corresponds to the odds ratio of t_i.

Value

A vector of odds ratios R=r_1, r_2,...,r_n-1,r_n where r_i corresponds to the odds ratio of t_i.

Examples

Given three contingency tables:
     setA  ¬setA          setA  ¬setA         setB  ¬setB
setB  3     100        setC  5     6        setD  20     45
¬setB  123   500       ¬setC  10    100     ¬setD  60     1000



a=c(3, 5, 20)
b=c(100, 6, 45)
c=c(123, 10, 60)
d=c(500, 100, 1000)
or = oddsRatio(a,b,c,d)
