THunc

a tool for computing theory uncertainties from missing higher orders


Author: Marco Bonvini
Developer: Marco Bonvini

THunc is a code that computes a probability distribution for a physical observable based on its perturbative expansion.
From the probability distribution a number of statistical estimators (mean, mode, median, standard deviation, degree of belief intervals) are also provided.
The calculation of the probability distribution is based on some assumptions, that are encoded into a model.
The models available in the code are In all cases one can also look for a sign pattern through the flag -P.
Scale independent results can be obtained using the flag -s [QCD only].
Use the -h option for help.

To set the process and/or to define a custom model, open the example_QCD.cc file and check its first part.
Obviously, the code must be recompiled after changes.
