Parameter Estimation & Calibration
Parameter Estimation & Model Calibration
Parameter estimation and model calibration may seem complicated, and you are correct if you don’t have software to help you make better informed decisions about your model. PEST has become a global phenomena with more and more professionals relying on PEST to help provide a better calibrated groundwater model. In addition to offering PEST, we also provide courses on practical approaches to calibrating your model. Give us a call for more information!
PEST and its utilities allow a user to undertake comprehensive linear and nonlinear parameter and predictive uncertainty analysis as an adjunct to calibration based on highly parameterized inversion. PEST is more than just software. It is a whole new way of doing real-world environmental modeling. Contact us today for more information!

-
PEST provides the means to get the most information possible out of your data and into your model.
-
It provides the means to assess the (often considerable) uncertainty associated with model parameters and predictions, even after a model has been calibrated.
-
PEST can tell you where model predictive uncertainty is coming from, and what data you need to gather to most effectively reduce it.
-
PEST implements both traditional parameter estimation based on the use of only a few parameters, as well as highly-parameterized, regularized inversion based on the use of hundreds (or even thousands) of parameters.
-
It implements both linear and nonlinear uncertainty analysis, including its unique, efficient and powerful “null-space Monte Carlo” methodology for rapid generation of many different calibration-constrained parameter fields.
-
PEST is supported by a plethora of utility software that expedites its use in conjunction with many widely-used environmental models.
