- Function Beta(ShapeAlpha, ShapeBeta, Minimum, Maximum)¶
Beta¶
The function Beta
draws a random value from a beta distribution.
Beta(
ShapeAlpha, ! (input) numerical expression
ShapeBeta, ! (input) numerical expression
Minimum, ! (optional) numerical expression
Maximum ! (optional) numerical expression
)
Arguments¶
- ShapeAlpha
A scalar numerical expression \(> 0\).
- ShapeBeta
A scalar numerical expression \(> 0\).
- Minimum
A scalar numerical expression.
- Maximum
A scalar numerical expression \(>\)min.
Return Value¶
The function
Beta
returns a random value drawn from a beta distribution with shapes ShapeAlpha, ShapeBeta, lower bound Minimum and upper bound Maximum.
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 Beta
(ShapeAlpha,
ShapeBeta, s) returns a random value drawn from a beta distribution
with shapes ShapeAlpha, ShapeBeta and scale s, where
\(s = Maximum\) and \(Minimum = 0\).

distribution is discussed in full detail in Discrete Distributions of
