Types ¶

type CentroidsT ¶

type CentroidsT []centroidT

CentroidsT is sorted by the mean of the centroidT, ascending.

func (CentroidsT) Len ¶

func (c CentroidsT) Len() int

type TDigest ¶

type TDigest struct {
	Data        CentroidsT
	TotalWeight weightT // total TotalWeight of all centroids
	Min, Max    weightT
}

func NewTDigest ¶

func NewTDigest(data []meanT, compression int) *TDigest

func (*TDigest) Merge ¶

func (t *TDigest) Merge(t2 *TDigest, compression int)

Merge of two TDigest structures is nothing more than add the centroids of one tDigest to the centroids of the other tDigest

func (*TDigest) Percentile ¶

func (t *TDigest) Percentile(p float32) float32

Percentile returns the (approximate) Percentile of the distribution. Accepted values for q are between 0.0 and 1.0. Returns NaN if count is zero or bad inputs.

func (*TDigest) Percentiles ¶

func (t *TDigest) Percentiles(p []float32) []float32

func (*TDigest) String ¶

func (t *TDigest) String() string
