AD Model Builder, or ADMB, the most powerful software package for the development of state-of-the-art nonlinear models, can now be freely downloaded for Windows, Linux, MacOS, and Sun/SPARC ADMB is a free and open source software suite for non-linear statistical modeling. It was created by David Fournier and now being developed by the ADMB Project, a creation of the non-profit ADMB Foundation. An extension of the language, ADMB-RE is available for modeling random effects. What is the advantage of using ADMB? The main advantages are speed, accuracy, stability, and the ability to build large models. ADMB has been estimated to perform faster at solving complex optimization problems than the numerical programming languages GAUSS, MATLAB, S-PLUS, and R. In one example, ADMB solved a minimization problem with 100 parameters in 3 seconds, while the "nlminb" function in R took 93 minutes to achieve the same solution (see http://otter-rsch.ca/tresults.htm for code of both models).
