The present work is concerned with a fast and accurate sequence comparison method: the count of the number of words of length k letters shared by two sequences, also known as the D2 statistic. We link recent theoretical advances in the characterization of D2 asymptotic distributions with applications to biological sequences. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
