TRngStream.RandomWeibull Method

void RandomWeibull(TMtxVec Dst, Double alpha, Double a, Double beta)

Generates an array of samples distributed by Weibull distribution.

Result: stored in self (calling object)

Remarks:

Returns random numbers distributed according to the Weibull probability density function (PDF) similar to as defined here Dew.Math.Units.Probabilities.WeibullPDF. The number of samples generated is defined with the Dst.Length parameter. The result is an array which can be accessed via Dst.Values property. The probability density function is defined as:

f(x) = (alpha (x-a)^(alpha-1))/beta^(alpha) exp(-((x-a)/beta)^(alpha)), x >= a f(x) = 0, x < a
