Misc

List. Miscellaneous output:

Creating Object

Objects can be created by calls of the form new("SMSE")

Details

In generation \(t\), proportionate natural influence (PNI) is defined as:

$$\textrm{PNI}_t = \dfrac{p^\textrm{NOB}_t}{p^\textrm{NOB}_t + p^\textrm{HOSeff}_t}$$

with \(p^\textrm{HOSeff} = \textrm{HOSeff}/(\textrm{NOS} + \textrm{HOSeff})\).

The proportion of wild salmon is defined as:

$$p^{\textrm{WILD}}_t = q^\textrm{HOScen}_t \dfrac{(q^\textrm{HOScen}_{t-1})^2} {(q^\textrm{HOScen}_{t-1})^2 + 2\gamma \times p^\textrm{HOScen}_{t-1} q^\textrm{HOScen}_{t-1} + \gamma^2 (p^\textrm{HOScen}_{t-1})^2}$$

where \(q = 1-p\) and \(p^\textrm{HOScen} = \textrm{HOS}/(\textrm{NOS} + \textrm{HOS})\).
