- Function Exponential(lowerbound, scale)¶
Exponential¶
The function Exponential
draws a random value from an exponential
distribution.
Exponential(
lowerbound ! (optional) numerical expression
scale ! (optional) numerical expression
)
Arguments¶
- lowerbound
A scalar numerical expression.
- scale
A scalar numerical expression \(> 0\).
Return Value¶
The function
Exponential
returns a random value drawn from a exponential distribution with 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
. The original function Exponential
(lambda) returns
a random value drawn from a exponential distribution with rate
\(lambda = 1/scale\) and lower bound \(0\).

distribution is discussed in full detail in Discrete Distributions
