ADMB or AD Model Builder is a free and open source software suite for non-linear statistical modeling.〔Fournier, D.A., H.J. Skaug, J. Ancheta, J. Ianelli, A. Magnusson, M.N. Maunder, A. Nielsen, and J. Sibert. 2012. AD Model Builder: using automatic differentiation for statistical inference of highly parameterized complex nonlinear models. Optim. Methods Softw. 27:233-249〕 It was created by David Fournier and now being developed by the ADMB Project, a creation of the non-profit ADMB Foundation. The "AD" in AD Model Builder refers to the automatic differentiation capabilities that come from the AUTODIF Library, a C++ language extension also created by David Fournier, which implements reverse mode automatic differentiation.〔(【引用サイトリンク】 publisher = ADMB Project )〕 A related software package, ADMB-RE, provides additional support for modeling random effects.〔(【引用サイトリンク】 publisher = ADMB Project )〕 ==Features and use== Markov chain Monte Carlo methods are integrated into the ADMB software, making it useful for Bayesian modeling.〔(【引用サイトリンク】 publisher = ADMB Project )〕 In addition to Bayesian hierarchical models, ADMB provides support for modeling random effects in a frequentist framework using Laplace approximation and importance sampling.〔 ADMB is widely used by scientists in academic institutions, government agencies, and international commissions,〔(【引用サイトリンク】 publisher=ADMB Project ) 〕 most commonly for ecological modeling. In particular, many fisheries stock assessment models have been built using this software.〔(【引用サイトリンク】 publisher=ADMB Project )〕 ADMB is freely available under the New BSD License,〔(【引用サイトリンク】 publisher=ADMB Project )〕 with versions available for Windows, Linux, Mac OS X, and OpenSolaris operating systems.〔 Source code for ADMB was made publicly available in March, 2009.〔(【引用サイトリンク】 publisher=University of California, Santa Barbara )〕 〔(【引用サイトリンク】 publisher=ADMB Project )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ADMB」の詳細全文を読む スポンサード リンク
