The ADMB framework is first tested on cod (Gadus morhua) data. In the first step, we start with a simple model [1] and an objective function [2]:
| Nt | = | Nt-1e-M-Ct | [1] |
|---|---|---|---|
| f(s,qt) | = | (2s2)-1[ln(qtNt)-ln(It)]2 | [2] |
| Parameter | Description | Dimension |
|---|---|---|
| N | ||
| M | ||
| C | ||
| I | ||
| s | ||
| q | ||
