Abstract
Provided is a method for sorting a number of samples into an appropriate number of clusters according to their characteristics. Highly-correlated peaks are extracted from mass spectrum data obtained for the samples (S). Using the extracted peaks, highly-correlated sample pairs are extracted (S). While removing samples having low degrees of correlation, highly-correlated sample pairs are integrated to form core clusters (S). Using singular peaks characterizing each core cluster, two or more core clusters are integrated to form clusters (S-S). These clusters include mixed clusters in which two or more clusters are mixed. Member determination formulae are created based on the singular peaks of each cluster (S-S). All samples, including those which have been excluded from the cluster determination process, are classified into clusters based on the member determination formulae (S). The member determination formulae can also be used to assign a new sample to one of the cluster.
