Cybergenetics study published on the validity of CPI match statistic

Pittsburgh, PA

“Inclusion probability for DNA mixtures is a subjective one-sided match statistic unrelated to identification information” was published today in the Journal of Pathology Informatics.The research article explains why the Combined Probability of Inclusion (CPI) always gives the same “one in a million” answer, but doesn’t give accurate match information.

CPI is a popular match statistic for DNA mixtures. CPI is equivalent to Combined Probability of Exclusion (CPE) and Random Man Not Excluded (RMNE). The peer-reviewed study shows that CPI behaves more like a random number generator than like a reliable measure of human identification.
