Parameters¶

Name	Description	Default	Range
`alpha`	alpha	1	\(\ge 0\)

The material type for a Weibull recruitment function is recruitment Weibull.

For this material the recruitment functions is given by

\[ F\left(\Xi\right)=1+r\left(1-\exp\left[-\left(\Xi/\mu\right)^{\alpha}\right]\right)\,. \]

Its minimum value is \(1\) and its maximum value is \(1+r\) as \(\Xi/\mu\to\infty\).

Example:

<recruitment type="recruitment Weibull">
  <mu>0.3</mu>
  <alpha>2.0</alpha>
  <max>4</max>
</recruitment>
