Description Details Slots Examples
A class that implement a biomass dynamic stock assessment model.
The Class is intended to be used as part of an MSE and includes methods for diagnostics, calculating reference points and other quantities used when providing management advice.
nameA character with the name of the stock
descA character providing a fuller description of the object
rangeA numeric vector containing the quant and year ranges
modelA factor giving name of production function, for now this is only 'pellat'
catchAn FLQuant with total catch by year
stockAn FLQuant which will hold the estimated stock by year
controlAn FLPar which sets initial guess (val) and bounds (min and max) for each parameter. The phase allows a parameter to be fixed if less <0 and for paramters to be estimated sequentially
hcrA data.frame with harvest contreol rule options
priorsAn array which sets penalties for parameters
paramsAn FLPar with parameter estmates
vcovAn FLPar with the covariance matrix of the parameter estimates
hessianAn FLPar with the hessian of the estimated parameters
refnumeric with parameters for estimating mng quantities
mngFLPar with derived quatities of management interest
mngVcovAn FLPar with the variance matrix of management quanties
diagsA data.frame with residuals and covariates from fit of CPUE to stock
objFnFLPar with objective function
llFLPar with negative log likelihood by data component
profiledata.frame not yet implemented
hstdata.frame not yet implemented
All slots in the class have accessor and replacement methods that provide validation and protection of their data.
