xproj: MCMC Projections from Cod Assessment

Description

Markov chain Monte Carlo projections from stock assessment of cod (Gadus morhua) in Icelandic waters.

Usage

xproj

Format

List containing two lists:

B	projected biomass by year, given a constant harvest rate policy: "0", "0.05", …, "0.50".
Y	projected catch by year, given a constant harvest rate policy: "0", "0.05", …, "0.50".

Details

MCMC projections can be used to evaluate the medium-term outcome of harvest policies (in this case, a certain fixed harvest rate), given the uncertainty about parameter values and random future recruitment.

See the x.cod help page for details about the data and model.
