Model Options

A variety of model options need to be specified to ensure the projection components of afscOM works as expected.

Paraemeter Name	Description	Dimensions	Default Value
removals_input	input units of removals (either “catch” is inputs are a total weight of catch, or “F” if an instantaneous fishing mortality rate)	-	“catch”
fleet_apportionment	Proportion of total catch allocated to each fishing fleet within each region	[nyears, nfleets, nregions]	1/nfleets/nregions
simulate_observations	Whether to simulate observations from the OM	-	TRUE
recruit_apportionment	Proportion of total recruits allocated to each region	[nyears, nregions]	1/nregions
recruit_apportionment_random	Whether recruitment apportionment should be fixed at the values provided directly to the model, or whether to perform a random multinomial sample using the provided input as the probability of recruitment to each region. Sample size for multinomial sample is 30.	-	FALSE
do_recruits_move	Whether annual recruits are subject to movement in the year they recruit.	-	TRUE

A helper function, setup_model_options() is provided to create a list of model options with the default values. This function does not set default values for observations parameters.
