Types

type Distribution

type Distribution interface {
	CDF(x float64) float64
	GetParams() Params
	GetName() string
	SetParams(slope, intercept float64)
	TransformX(x float64) float64
	TransformY(y float64) float64
}

Distribution represents an extreme value distribution. There are six implementations: FréchetMax/Min, GumbelMax/Min and WeibullMax/Min.

type Params

type Params map[string]float64

Params maps the names of distribution parameters to their values.

type WeibullMax

type WeibullMax struct {
	Loc   float64
	Scale float64
	Shape float64
}

WeibullMax represents a Weibull Maximum distribution.

func (WeibullMax) CDF

func (w WeibullMax) CDF(x float64) float64

CDF computes the value of the cumulative density function at x.

func (WeibullMax) GetName

func (w WeibullMax) GetName() string

GetName returns the name of the distribution.

func (WeibullMax) GetParams

func (w WeibullMax) GetParams() Params

GetParams returns parameters map.

func (*WeibullMax) SetParams

func (w *WeibullMax) SetParams(slope, intercept float64)

SetParams calculates, sets and returns distribution parameters from linear regression parameters.

func (WeibullMax) TransformX
