pearson.dist: Calculate Distance based on Pearson's R^2
Description
The calculated distance is
$D^2 = \frac{1 - COR (\code{x}')}{2}$
Usage
pearson.dist(x)
Arguments
x
a matrix
Value
distance matrix (distance object)
Details
The distance between the rows of x is calculated.
The possible values range from 0 (prefectly correlated) over 0.5 (uncorrelated) to 1 (perfectly anti-correlated).
