| − | In determining which model class has the largest [[posterior odds ratio]] ratio (of which the ''Bayes factor'' is a principle component) when compared against all others, the model class or [[mathematical model]] which best explains the data is determined. It is then left to determine the best inference as to the values of that models parameters via [[parameter estimation]]. | + | In determining which model class has the largest [[posterior odds ratio]] (of which the ''Bayes factor'' is a principle component) when compared against all others, the model class or [[mathematical model]] which best explains the data is determined.
