Predict length given VBGF parameters
External estimation procedure for von Bertalanffy growth.
vbgf_func(L1, L.inf, k, ages, a3)
L1
: mean length at youngest age which is well sampled in the data (a3)L.inf
: Length at infinityk
: von Bertalanffy growth rate parameterages
: vector of ages in the data for which you want to predict mean length-at-agea3
: youngest age which is well sampled in the dataa vector of lengths predicted which correspond to the input ages vector.
