Parameter estimation using PEST

Simile 4.5 includes built-in support for the PEST software tool for model calibration, parameter estimation and predictive uncertainty analysis.

PEST is an advanced software tool for model calibration, parameter estimation and predictive uncertainty analysis. It is open-source and freely available, and currently distributed by S. S. Papadopoulos & Associates, Inc.

The Simile PEST interface is a set of forms that allow parameter estimation to be carried out using PEST from within Simile's model execution environment. This will enable Simile users to do various kinds of model analysis without needing to know about PEST's file formats etc. View the online help for more information.
