DNA evidence is widely used in the modern justice system. Statistical
methodology plays a key role in ensuring that this evidence is
collected, interpreted, analysed and presented correctly. This book is a
guide to assessing DNA evidence and presenting that evidence in a
courtroom setting. It offers practical guidance to forensic scientists
with little dependence on mathematical ability, and provides the
scientist with the understanding they require to apply the methods in
their work. Since the publication of the first edition of this book in
2005 there have been many incremental changes, and one dramatic change
which is the emergence of low template DNA (LTDNA) profiles. This second
edition is edited and expanded to cover the basics of LTDNA technology.
The author's own open-source R code likeLTD is described and used for
worked examples in the book. Commercial and free software are also
covered.
