Properties
  NameDescription
Public propertyKurtosis
Gets the kurtosis, a measure of the degree of peakednesss of the distribution.
Public propertyMean
Gets the mean of the distribution.
Public propertyScale
Gets and sets the scale parameter for the distribution. The scale parameter must be positive.
Public propertyShape
Gets and sets the shape parameter for the distribution. The shape parameter must be positive.
Public propertySkewness

Methods
  NameDescription
Public methodCDF
Returns the cumulative density function evaluated at a given value.
(Overrides ProbabilityDistributionCDF(Double).)
Public methodClone
Creates a deep copy of this WeibullDistribution.
(Overrides ProbabilityDistributionClone.)
Public methodStatic memberFit
Fits a Weibull distribution to observed data. The scale and shape parameters for the Weibull distribution are estimated and the corresponding Weibull distribution object returned. If the fit is not successful null is returned.
Public methodInverseCDF
Returns the inverse cumulative density function evaluated a the given value.
(Overrides ProbabilityDistributionInverseCDF(Double).)
Protected methodInverseCdfUsingBracket
Uses a bracketing method to evaluate the inverse of cumulative distribution functions.
(Inherited from ProbabilityDistribution.)
Protected methodInverseDiscreteCdfUsingBracket
Uses a bracketing method to evaluate the inverse of cumulative distribution functions for discrete distributions.
(Inherited from ProbabilityDistribution.)
Public methodPDF
Returns the probability density function evaluated at a given value.
(Overrides ProbabilityDistributionPDF(Double).)
Public methodSetParameters
Sets the scale and shape parameter for this distribution.
Public methodToString
Returns a formatted string representation of this distribution.
(Overrides ProbabilityDistributionToString.)

Remarks
The probability density function of the Weibull distribution is given by: f(x;k,a) = (k/a)*(x/a)^(k-1)*exp(-(x/a)k)
