Usage
type Params
type Params struct {
Compression float64
}
Params implements dist.Params for a t-digest distribution.
func (Params) Kind
func (p Params) Kind() string
Kind returns the TDigest distribution kind.
func (Params) New
func (p Params) New() (dist.Dist, error)
New returns a new TDigest as a dist.Dist.
func (Params) Unmarshal
func (p Params) Unmarshal(data []byte) (dist.Dist, error)
Unmarshal loads a dist.Dist out of some bytes.
type Wrapper
type Wrapper struct {
}
Wrapper implements dist.Dist for a t-digest.
func Wrap
func Wrap(td *tdigest.TDigest) *Wrapper
Wrap wraps the given t-digest.
func (*Wrapper) CDF
func (w *Wrapper) CDF(x float64) float64
CDF returns the estimate CDF at the value x.
func (Wrapper) Kind
func (Wrapper) Kind() string
Kind returns the string "tdigest".
func (Wrapper) Len
func (w Wrapper) Len() int64
Len returns how many items were added to the t-digest.
func (Wrapper) Marshal
func (w Wrapper) Marshal(buf []byte) []byte
Marshal appends a byte form of the t-digest to the provided buffer.
func (Wrapper) Observe
func (w Wrapper) Observe(val float64)
Observe adds the value to the t-digest.
