useful as an aid to model calibration is this:- if a model-generated time series is to be compared with an observed time series, and/or various TSPROC-calculated functions of the former are to be compared with identical functions of the latter as part of the calibration process, TSPROC can generate an appropriate set of PEST input files by PEST is a model-independent parameter estimation package which can communicate with any model through the model's own input and output files. PEST can be used for nonlinear parameter estimation and predictive analysis in many different fields of study including ground and surface water hydrology, geophysics, engineering and others. PEST can calibrate models encapsulated in batch or script files of arbitrary complexity. Other PEST features include: Individual model parameters can be designated as adjustable, fixed, or linked to other parameters; adjustable parameters can be log-transformed to increase optimization efficiency. The PEST calibration is conducted by using various linear techniques to minimize the objective function.

Another aspect of the design of TSPROC that makes it ideally suited for use in a calibration context is that time series manipulation carried out by TSPROC does not PEST is revolutionizing model calibration. In hydrology, engineering, geophysics, biology, economics and many other fields, PEST is changing the way people work with models. Nonlinear parameter estimation has never been this easy or this robust.

As a complement to functionality that it provides for highly parameterized inversion (calibration) by means of 2019-04-17 · Parameter estimation using PEST can assist in data interpretation, model calibration, and predictive analysis. PEST can do a lot for your project. Because PEST offers so much, it can be a little overwhelming to use at first. We provide tutorials and articles on our wiki to help guide you in using PEST with GMS. PEST called BeoPEST was successfully useful to speed up calibration process.
