Detailed Description

The Weibull distribution Random Number Generator (RNG) that allows stream numbers to be set deterministically.


This class supports the creation of objects that return random numbers from a fixed Weibull distribution. It also supports the generation of single random numbers from various Weibull distributions.

The probability density function is defined over the interval [0, $+\infty$] as: $ \frac{k}{\lambda}\left(\frac{x}{\lambda}\right)^{k-1}e^{-\left(\frac{x}{\lambda}\right)^k} $ where $ k > 0$ is the shape parameter and $ \lambda > 0$ is the scale parameter. The specified mean is related to the scale and shape parameters by the following relation: $ mean = \lambda\Gamma\left(1+\frac{1}{k}\right) $ where $ \Gamma $ is the Gamma function.

Since Weibull distributions can theoretically return unbounded values, it is sometimes useful to specify a fixed upper limit. Note however when the upper limit is specified, the true mean of the distribution is slightly smaller than the mean value specified.

Here is an example of how to use this class:

double scale = 5.0;
double shape = 1.0;
Ptr<WeibullRandomVariable> x = CreateObject<WeibullRandomVariable> ();
x->SetAttribute ("Scale", DoubleValue (scale));
x->SetAttribute ("Shape", DoubleValue (shape));
// The expected value for the mean of the values returned by a
// Weibull distributed random variable is
//
// E[value] = scale * Gamma(1 + 1 / shape) ,
//
// where Gamma() is the Gamma function. Note that
//
// Gamma(n) = (n - 1)!
//
// if n is a positive integer.
//
// For this example,
//
// Gamma(1 + 1 / shape) = Gamma(1 + 1 / 1)
// = Gamma(2)
// = (2 - 1)!
// = 1
//
// which means
//
// E[value] = scale .
//
double value = x->GetValue ();

◆ GetInteger() [1/2]

uint32_t ns3::WeibullRandomVariable::GetInteger ( uint32_t  scale,

Parameters
[in]scaleScale parameter for the Weibull distribution.
[in]shapeShape parameter for the Weibull distribution.
[in]boundUpper bound on values returned.

is a value that would be returned normally, then $(1 - u$) is the distance that $u$ would be from $1$. The value returned in the antithetic case, $x'$, is calculated as

\[ x' = scale * {(-\log(1 - u))}^{\frac{1}{shape}} , \]
