Examples using AD Model Builder

These examples include the users TPL file (that is the template), the CPP file (C++ source code) produced from the template, the compiled executable and the DAT file (data input to the model). These files are in PKZIP format. They have been compiled with the DJGPP v2 C++ compiler for DOS. They are DPMI32 compatible and will run in a window under Windows 95 or NT. To run them in DOS you will need to download the zip file CWSDPMI.ZIP and extract the file CWSDPMI.EXE from it (and put it in a directory on your path). Examples for other platforms can be supplied. Contact us.

Click on DOCS for an online description of the example or on the file name to download the example file. Some trouble with reading the DOCS with Internet Explorer has been reported. We recommend using NETSCAPE.

• DOCS SIMPLE.ZIP -- a very simple example to illustrate the idea.
  
• DOCS TRUNCREG.ZIP-- a truncated linear regression.
  
• DOCS BUSCYCLE.ZIP -- an implementation of the domain switching model described in Hamilton (1989). We have implemented the fourth order autoregressive model described in the paper as well as extending the model to a fifth order autoregressive process in accordance with the author's remarks on page 372 to illustrate the flexibility of the AD Model Builder modeling package.

• DOCS CATAGE.ZIP -- a catch at age model for fisheries management.
  
• NEW !! DOCS VOL.ZIP -- a stochastic volatility model using a generalized Kalman filter.
  
• DOCS FINANCE.ZIP -- a simple GARCH model used in financial modeling.
  
• DOCS ROBREG.ZIP -- illustrates the use of robust nonlinear regression.
  
• DOCS PELLA-T.ZIP -- another model used in fisheries management.
  
• DOCS CHEM-ENG.ZIP -- a chemical engineering model using a system of ODE's.
  
• DOCS FOREST.ZIP -- A forestry model to estimate parameters which influence the size distribution of wildfires. This model illustrates the use of numerical integration within the parameter estimation process.

Documentation for Downloading

Download zipped PDF file adm.zip for AD Model Builder DOCUMENTATION There is also a zipped pdf aut.zip for AUTODIF DOCUMENTATION upon which AD Model Builder is based.
(NOTE: AD Model builder and AUTODIF take a somewhat different point of view about how to build models for nonlinear parameter estimation so that it is better to read the AD Model Builder documentation first.)
NOTE: These are ZIP files not EXE's. Some browsers want to name them incorrectly.
