no-herd Hugo.Mildenberger@web.de The ADMB(Automatic Differentiation Model Builder) software suite is an environment for non-linear statistical modeling enabling rapid model development, numerical stability, fast and efficient computation, and high accuracy parameter estimates. ADModel Builder is a high level language built around the AUTODIF Library, a C++ language extension which transparently implements reverse mode automatic differentiation. A closely related software package, ADMB-RE, implements random effects in non-linear models.
