LBSPRsim(LB_pars = NULL, Control = list(), verbose = TRUE)
LB_pars | an object of class |
---|---|
Control | a list of control options for the LBSPR model. |
verbose | display messages? |
a object of class 'LB_obj'
The Control options are:
modtype
Model Type: either Growth-Type-Group Model (default: "GTG") or Age-Structured ("absel")
maxsd
Maximum number of standard deviations for length-at-age distribution (default is 2)
ngtg
Number of groups for the GTG model. Default is 13
P
Proportion of survival of initial cohort for maximum age for Age-Structured model. Default is 0.01
Nage
Number of pseudo-age classes in the Age Structured model. Default is 101
maxFM
Maximum value for F/M. Estimated values higher than this are trunctated to maxFM
. Default is 4
