newtype Dist a Source #

Type synonym for column vector matrices. This represents a probability distribution.

Constructors

type Prob = Double Source #

Type synonym for probability value

type Countable a = KnownNat (Count a) Source #

Constraint type synonyms to keep the type signatures less convoluted
