Markov chain Monte Carlo projections from stock assessment of cod (Gadus morhua) in Icelandic waters.
List containing two lists:
|| projected biomass by year, given a constant harvest
|| projected catch by year, given a constant harvest rate
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.
