Patent ID: 8024155

Claim:
A sample data reliability evaluation method comprising: a first calculating step of calculating a representative distance between samples of a same cluster, which is a representative distance between one sample and at least one other sample, the one sample and the at least one other sample belonging to the same cluster, based on a sample data set having a plurality of pieces of sample data concerning clustered samples as elements; a second calculating step of calculating a representative distance between samples of different clusters, which is a representative distance between the one sample and at least one different sample, the at least one different sample belonging to a different cluster from the cluster of the one sample, based on the sample data set; a third calculating step of calculating a reliability evaluation index, which is an index for evaluating reliability of the sample data based on the representative distance between samples of the same cluster calculated at the first calculating step and the representative distance between samples of different clusters calculated at the second calculating step; and an evaluating step of evaluating the reliability of a subset of the sample data set or a whole of the sample data set based on the reliability evaluation index calculated at the third calculating step.
