LBSPR_NLLabsel.RdInternal optimization function
LBSPR_NLLabsel(starts, x, P, LMids, LBins, LDat, MK, Linf, FecB, L50, L95, maxsd, CVLinf, Nage, usePen)
| starts | a vector of starting parameters, relative SL50 (SL50/Linf), deltaSL (SL95-SL50)/Linf, and F/M (in log space) |
|---|---|
| x | vector of relative ages |
| P | numeric value indicating proportion of cohort remaining at maximum age |
| LMids | a vector of the midpoints of the length classes |
| LBins | a vector of length classes |
| LDat | a vector of lenght frequencies. Must be same length as LMids |
| MK | the M/K value |
| Linf | the Linf value for the population as a hole |
| FecB | exponent of the length-fecundity relationship |
| L50 | length at 50 per cent maturity |
| L95 | length at 95 per cent maturity |
| maxsd | numeric value - maximum number of standard deviations of length-at-age dist |
| CVLinf | CV of length-at-age |
| Nage | number of pseudo age-classes |
| usePen | logical to use penalty for extreme estimates of selectivity |
negative log-likelihood value
