Function Weibull(Shape, Lowerbound, Scale)

# Weibull

The function Weibull draws a random value from a Weibull distribution.

Weibull(
Shape,       ! (input) numerical expression
Lowerbound,  ! (optional) numerical expression
Scale        ! (optional) numerical expression
)


## Arguments

Shape

A scalar numerical expression $$> 0$$.

Lowerbound

A scalar numerical expression.

Scale

A scalar numerical expression $$> 0$$.

## Return Value

The function Weibull returns a random value drawn from a Weibull distribution with shape Shape lower bound Lowerbound, and scale Scale.

Note

The prototype of this function has changed with the introduction of AIMMS 3.4. In order to run models that still use the original prototype, the option Distribution_compatibility should be set to Aimms_3_0. In the original function Weibull(Lowerbound, Shape, Scale), the arguments were ordered differently.

The Weibull distribution is discussed in full detail in Discrete Distributions of the Language Reference.
