func FlatMap ¶

func FlatMap[T any, U any](
	dist Dist[T],
	mapper func(T) Dist[U],
) (Dist[U], error)

FlatMap maps each outcome of a probability distribution of outcome T to a new probability distribution with outcome U and flattens the results into a single distribution of outcome U

func FromConst ¶

func FromConst[T any](v T) (Dist[T], error)

FromConst returns a distribution whose sole outcome is v

func FromEntries ¶

func FromEntries[T any](m []EntryT[T]) (Dist[T], error)

func FromMap ¶

func FromMap[T comparable](m MapT[T]) (Dist[T], error)

func Map ¶

func Map[T any, U any](
	dist Dist[T],
	mapper func(T) U,
) (Dist[U], error)

Map maps a probability distribution from outcome type T to U

func Reduce ¶

func Reduce[T any, U any](
	dists []Dist[T],
	collector func(U, T) U,
	initialValue U,
) (Dist[U], error)

reduces probability distributions of multiple independent events into an aggregate probability distribution
