and Auxiliary Computer Codes
for Universal Sensitivity Analysis,
Calibration, and Uncertainty Evaluation
UCODE_2014 completely supersedes UCODE_2005 and is
backward compatible with UCODE_2005
UCODE_2014 is documented using two reports: the
documentation for UCODE_2005 and a new report for UCODE_2014
using the JUPITER API
JUPITER: Joint Universal Parameter IdenTification and Evaluation of
API: Application Programming Interface

UCODE_2014 version 1.004 along with OPR-PPR, MMA, and SIM-Adjust
installation instructions see readme_ucode_2014.txt)
self-extracting zip file ucode_2014_1.004.exe
for a PC, source and test files:
place in root directory and extract, directory wrdapp/ucode_2014_1.004
will be created if it does not yet exist
This distribution of UCODE_2014
includes three programs often used with UCODE
OPR-PPR calculates measures of data importance to model predictions.
The quantities evaluated are observations (targets) and parameters from
Thus, OPR-PPR provides statistics that quantify the link between
observations and predictions (the statistic
is called OPR) and the link between parameters and predictions (the
statistic is called PPR).
MMA supports the use of multiple alternative models. The models may
differ in the included processes,
parameterization methods, and in other ways. All models need to be
evaluated using the same set of observations.
SIM_Adjust allows the user to manage circumstances in which the
simulated equivalent for one or mode observations
is not produced. The user can define an alternate simulated value or
constant to be used instead.
