Syntax

public static double Weibull(
	double x,
	double gamma,
	double alpha
)

Public Shared Function Weibull ( 
	x As Double,
	gamma As Double,
	alpha As Double
) As Double

public:
static double Weibull(
	double x, 
	double gamma, 
	double alpha
)

static member Weibull : 
        x : float * 
        gamma : float * 
        alpha : float -> float

x: Type: SystemDouble
A double scalar value representing the argument at which the function is to be evaluated. It must be non-negative.
gamma: Type: SystemDouble
A double scalar value representing the shape parameter, $\gamma$ .
alpha: Type: SystemDouble
A double scalar value representing the scale parameter, $\alpha$ .

Type: Double
A double scalar value representing the probability that a Weibull random variable takes a value less than or equal to x.

Remarks

Method Cdf.Weibull evaluates the distribution function given by

$F(x,\gamma,\alpha)=1-e^{-(x/\alpha)^{ \gamma}}$
