rpay-class {FLEDA} | R Documentation |
This class encapsulates results of a rpay
method.
Objects of this classe should be created with a call to the contructor function rpay(object, ...)
, where object
must be an object of class "FLQuant"
and ...
can be used to pass trim
arguments to the creator funtion.
"FLQuant"
.
Class "FLQuant"
, directly.
Inherits from "FLQuant"
.
Considering C_{ay}, the catch in numbers at age a=1,...,A per year y=1,...,Y, obtained e.g. from the catch.n slot of a "FLStock"
object, the computation of rpay
P_{ay}^r is:
Consider:
P_{ay}=frac{C_{ay}}{sum_a{C_{ay}}}
and
bar{P}_{a}=frac{sum_y{P_{ay}}}{Y}
P_{ay}^r=frac{P_{ay}}{bar{P}_{a}}
