AD Model Builder
AD Model Builder (ADMB) provides a powerful framework for the estimation of parameters (and their variances, co-variances) for (highly) non-linear models. It is a great program when everything works, but getting there can often be long and arduous. So this page is intended to share some pointers and examples for using AD Model Builder (ADMB).
