Types

type D

type D struct {
	// contains filtered or unexported fields
}

D is a distribution. Methods of D can be called concurrently by multiple goroutines.

func New

func New(n int) *D

New creates a new distribution capable of holding values from 0 to n-1.

func (*D) Percentile

func (d *D) Percentile(p float64) int

Percentile computes the p-th percentile of the distribution where p is between 0 and 1.

func (*D) Record

func (d *D) Record(v int)

Record records value v to the distribution. To help with distributions with long tails, if v is larger than the maximum value, Record records the maximum value instead. If v is negative, Record panics.
