PEST - Model-Independent Parameter Estimation and Uncertainty Analysis

PEST:

Model-Independent Parameter Estimation
and Uncertainty Analysis

Welcome to the PEST web pages.


PEST is the industry standard software package for parameter estimation and uncertainty analysis of complex environmental and other computer models.
PEST is:
  • state-of-the art;
  • comprehensively documented;
  • accompanied by a plethora of utility programs that support its use in conjunction with widely-used groundwater and surface water models;
  • free.
Stroll through these pages to:
  • find out what PEST does;
  • download PEST;
  • download a comprehensive PEST tutorial; 
  • learn about upcoming PEST events;
  • meet other PEST users.
Coming soon - PEST - the Book

This will bring together in one place all of the theory on which PEST and its suite of utility software is based. It will also cover important issues like how models should be used in the decision-making context, uncertainty analysis, model-based hypothesis testing, and the effects of model defects on calibration, prediction and uncertainty analysis. This will make an essential reference text for those engaged in environmental modelling.
