Application of simple Bayesian statistics to a sample database for source correspondence.
Bayesian statistics was applied to a small sample database of the tensile properties of five different brands of writing paper which were perceptibly similar. The measured parameters in the database were found to overlap for the five brands. This posed a limitation to the application of the classical approach for "match" or "no match". It was found that using Bayesian statistics for source correspondence, a mere 2-3 measurements corresponding to a particular brand raised the probabilities associated with that brand to as high a 72% and eliminating a couple of brands.
