Description

Collection of some shapes of distribution.

Synopsis

type T prob = prob -> prob linear :: Fractional prob => T prob uniform :: Fractional prob => T prob negExp :: Floating prob => T prob normal :: Floating prob => T prob normalCurve :: Floating prob => prob -> prob -> prob -> prob

Documentation

type T prob = prob -> prob Source

A shape is a mapping from the interval [0,1] to non-negative numbers. They need not to be normalized (sum up to 1) because this is done by subsequent steps. (It would also be impossible to normalize the function in a way that each discretization is normalized as well.)

linear :: Fractional prob => T prob Source

uniform :: Fractional prob => T prob Source

negExp :: Floating prob => T prob Source

normal :: Floating prob => T prob Source

normalCurve :: Floating prob => prob -> prob -> prob -> prob Source
