SP_production R Documentation
Find the production parameter based on depletion that produces MSY
Description
For surplus production models, this function returns the production exponent n corresponding
to BMSY/K (Fletcher 1978).
Usage
SP_production(depletion, figure = TRUE)
Arguments
depletion
The hypothesized depletion that produces MSY.
figure
Local, plots figure of production function as a function of depletion (B/K)
Value
The production function exponent n (numeric).
Note
May be useful for parameterizing n in SP and SP_SS.
