The use of statistical and probabilistic ideas in forensic scienceis of increasing importance to the administration of justice. Thisis exemplified by their role in the evaluation and interpretationof trace evidence, such as glass, fibres and DNA. They allow theforensic scientist to evaluate and interpret evidence where thereis an element of uncertainty. For many years, Statistics and the Evaluation of Evidence forForensic Scientists has been considered the leading text in thestatistical evaluation of forensic evidence. It is highly regardedamongst forensic scientists. This new edition is fully updated,covering many new topics of interest, and includes coverage of newfields of evidence. It features new examples concerned withup-to-date data sets, and a chapter on evidence evaluation usingBayesian nets. Provides a comprehensive introduction to the statisticalevaluation of forensic evidence. Features new material on glass interpretation, fibresinterpretation and Bayesian nets. Includes new material on the analysis of multi variate data,useful, for example, in problems involving elemental or chemicalcompositions. Illustrated throughout with examples using real up-to-datedata. Assumes only a modest mathematical background. Includes a foreword by Dennis Lindley. The clarity of exposition makes this book ideal for all forensicscientists, lawyers and other professionals in related fieldsinterested in the quantitative assessment and evaluation offorensic evidence. It is also suitable for graduate studentsstudying courses in the statistical evaluation of evidence. 'There can be no doubt that the appreciation of some evidencein a court of law has been greatly enhanced by the sound use ofstatistical ideas and one can be confident that the next decadewill see further developments, during which time this book willadmirably serve those who have cause to use statistics in forensicscience.'

Genre: Law

Statistical methods provide a logical, coherent framework in which data from experimental science can be analyzed. However, many researchers lack the statistical skills or resources that would allow them to explore their data to its full potential. Introduction to Data Analysis with R for Forensic Sciences minimizes theory and mathematics and focuses on the application and practice of statistics to provide researchers with the dexterity necessary to systematically analyze data discovered from the fruits of their research. Using traditional techniques and employing examples and tutorials with real data collected from experiments, this book presents the following critical information necessary for researchers: A refresher on basic statistics and an introduction to R Considerations and techniques for the visual display of data through graphics An overview of statistical hypothesis tests and the reasoning behind them A comprehensive guide to the use of the linear model, the foundation of most statistics encountered An introduction to extensions to the linear model for commonly encountered scenarios, including logistic and Poisson regression Instruction on how to plan and design experiments in a way that minimizes cost and maximizes the chances of finding differences that may exist Focusing on forensic examples but useful for anyone working in a laboratory, this volume enables researchers to get the most out of their experiments by allowing them to cogently analyze the data they have collected, saving valuable time and effort.

Statistical Analysis in Forensic Science

Author: Grzegorz Zadora
Publisher: John Wiley & Sons
ISBN: 9780470972106
Release Date: 2014-02-03
Genre: Mathematics

A practical guide for determining the evidential value of physicochemical data Microtraces of various materials (e.g. glass, paint, fibres, and petroleum products) are routinely subjected to physicochemical examination by forensic experts, whose role is to evaluate such physicochemical data in the context of the prosecution and defence propositions. Such examinations return various kinds of information, including quantitative data. From the forensic point of view, the most suitable way to evaluate evidence is the likelihood ratio. This book provides a collection of recent approaches to the determination of likelihood ratios and describes suitable software, with documentation and examples of their use in practice. The statistical computing and graphics software environment R, pre-computed Bayesian networks using Hugin Researcher and a new package, calcuLatoR, for the computation of likelihood ratios are all explored. Statistical Analysis in Forensic Science will provide an invaluable practical guide for forensic experts and practitioners, forensic statisticians, analytical chemists, and chemometricians. Key features include: Description of the physicochemical analysis of forensic trace evidence. Detailed description of likelihood ratio models for determining the evidential value of multivariate physicochemical data. Detailed description of methods, such as empirical cross-entropy plots, for assessing the performance of likelihood ratio-based methods for evidence evaluation. Routines written using the open-source R software, as well as Hugin Researcher and calcuLatoR. Practical examples and recommendations for the use of all these methods in practice.

Introduction to Statistical Methods in Modern Genetics

Author: M.C. Yang
Publisher: CRC Press
ISBN: 9056991345
Release Date: 2000-02-23
Genre: Mathematics

Although the basic statistical theory behind modern genetics is not very difficult, most statistical genetics papers are not easy to read for beginners in the field, and formulae quickly become very tedious to fit a particular area of application. Introduction to Statistical Methods in Modern Genetics distinguishes between the necessary and unnecessary complexity in a presentation designed for graduate-level statistics students. The author keeps derivations simple, but does so without losing the mathematical details. He also provides the required background in modern genetics for those looking forward to entering this arena. Along with some of the statistical tools important in genetics applications, students will learn: How a gene is found How scientists have separated the genetic and environmental aspects of a person's intelligence How genetics are used in agriculture to improve crops and domestic animals What a DNA fingerprint is and why there are controversies about it Although the author assumes students have a foundation in basic statistics, an appendix provides the necessary background beyond the elementary, including multinomial distributions, inference on frequency tables, and discriminant analysis. With clear explanations, a multitude of figures, and exercise sets in each chapter, this text forms an outstanding entrée into the rapidly expanding world of genetic data analysis.

A Hands On Introduction to Forensic Science

Author: Mark Okuda
Publisher: CRC Press
ISBN: 9781482234923
Release Date: 2014-10-17
Genre: Law

One failing of many forensic science textbooks is the isolation of chapters into compartmentalized units. This format prevents students from understanding the connection between material learned in previous chapters with that of the current chapter. Using a unique format, A Hands-On Introduction to Forensic Science: Cracking the Case approaches the topic of forensic science from a real-life perspective in a way that these vital connections are encouraged and established. The book utilizes an ongoing fictional narrative throughout, entertaining students as it provides hands-on learning in order to "crack the case." As two investigators try to solve a missing persons case, each succeeding chapter reveals new characters, new information, and new physical evidence to be processed. A full range of topics are covered, including processing the crime scene, lifting prints, trace and blood evidence, DNA and mtDNA sequencing, ballistics, skeletal remains, and court testimony. Following the storyline, students are introduced to the appropriate science necessary to process the physical evidence, including math, physics, chemistry, and biology. The final element of each chapter includes a series of cost-effective, field-tested lab activities that train students in processing, analyzing, and documenting the physical evidence revealed in the narrative. Practical and realistic in its approach, this book enables students to understand how forensic science operates in the real world.
