Random values
random distribution
type Distribution prob a = T (T prob a) Source
Randomized distribution
above :: (Num prob, Ord prob, Ord a) => prob -> Distribution prob a -> Distribution prob (Select a) Source
below :: (Num prob, Ord prob, Ord a) => prob -> Distribution prob a -> Distribution prob (Select a) Source
dist :: (Fractional prob, Ord a) => [T a] -> Distribution prob a Source
dist converts a list of randomly generated values into
a distribution by taking equal weights for all values.
Thus dist (replicate n rnd) simulates rnd n times
and returns an estimation of the distribution represented by rnd.
