Description
The Yule coefficient of is a correlation coefficient applied
to dichotomous data. Given a two x two table of counts
a b R1
c d R2
C1 C2 n
or a vector c(a,b,c,d) of frequencies.
Usage
1
Yule(x)
Arguments
x
a 1 x 4 vector or a matrix 2 x 2 of frequencies.
Y
if Y is true return Yule's Y coefficient of colligation.
Details
The coefficient of Yule is calculated from (ad - bc)/(ad + bc).
This is the number of pairs in agreement (ad) - the number in disagreement (bc)
over the total number of paired observations.
Value
the value of the Yule Q coefficient.
