zipf: Zipf's law
In RobinHankin/hyper2: The Hyperdirichlet Distribution, Mark 2
zipf R Documentation
Zipf's law
Description
A very short function that reproduces Zipf's law: a harmonic rank-probability
distribution, formally
p(i)=\frac{i^{-1}}{\sum_{i=1}^{N} i^{-1}},\qquad i=1,\ldots,N
The volleyball dataset might reasonably be assumed to be zipf, but one
can reject this hypothesis at 5\%, see the examples.
Usage
zipf(n)
Arguments
n
Integer; if a hyper2 object is supplied this is
interpreted as size(n)
Value
Returns a numeric vector summing to one
