Index of Association
Description
This is a very basic index of association (IOA). It simply counts how often
two vectors increase or decrease in parallel.
Usage
ioa(x, y)
Arguments
x
a numeric vector
y
a numeric vector
Value
numeric between 0 and 1. 0 means the two vectors are always
changing in opposite directions, 1 means they are always changing
in identical directions

set.seed(123)
d <- rnorm(100, 7, 1)
set.seed(234)
e <- rnorm(100, 200, 10)
ioa(a, b)
