PEST Version 10 Beta Release

PEST v10 will be released later this year. A beta version can be downloaded
from ( http://www.sspa.com/pest/download.html) for those interested in
exploring recent developments in model predictive uncertainty analysis.
Enhancements to the capabilities of PEST in v10 include:

* PEST’s SVD-assist scheme has been enhanced, enabling regularized inversion
to be used with highly parameterized models with efficiencies commensurate
with traditional parameter estimation.
* PEST’s predictive analyser is more powerful, with an improved line-search
algorithm and added functionality to encompass the effects of predictive
noise on predictive variability.
* A greatly expanded suite of utility software supports:
* Comprehensive post-processing of PEST results including analysis and
plotting of the resolution matrix and other by-products of the regularized
inversion process.
* Quantification of the contribution to pre- and/or post-calibration error
variance of important model predictions by individual parameters or
different parameter types.
* Data acquisition analysis - assess the value of making extra measurements
of system state (e.g., water level) or of system properties (e.g.,
transmissivity) in terms of predictive error variance reduction, in advance
of acquiring those data.

Moore and Doherty (Water Resources Research, May 2005) show that traditional
predictive uncertainty analyses can underestimate true variability by
neglecting complexity that it is beyond the ability of the calibration
process to capture. PEST Version 10 provides access to the methodologies
presented in that paper that support the analysis of predictive error
variance as an adjunct to regularized inversion.
