These tutorials show how to use the CERN minimization package Minuit (developed by Dr. Fred James) to fit simple cosmological models to the Union 2.1 Type1a supernova data. Minuit, which is available in the CERN data analysis package ROOT, can be used directly or via the probability modeling package RooFit. Both ways are illustrated in these tutorials.
