About this book

Since the publication of the first edition, the field of microarrays has evolved. This timely second edition replaces the commercial software with the open source R computing environment. Although R code is integrated into the text, users of other programming languages can still benefit from Statistics and Data Analysis for Microarrays Using R and Bioconductor. This edition contains new chapters on cutting-edge microarray topics and provides the R code on an accompanying CD-ROM. Richly illustrated in full color, Statistics and Data Analysis for Microarrays Using R and Bioconductor continues to bridge the gap between an introduction to data analysis and advanced material for performing data analysis.

Praise for the First Edition

"The book by Drăghici is an excellent choice to be used as a textbook for a graduate-level bioinformatics course. This well-written book with two accompanying CD-ROMs will create much-needed enthusiasm among statisticians."
- Journal of Statistical Computation and Simulation, Vol. 74

"I really like Drăghici's book. As the author explains in the Preface, the book is intended to serve both the statistician who knows very little about DNA microarrays and the biologist who has no expertise in data analysis. The author lays out a study plan for the statistician that excludes 5 of the 17 chapters (4-8). These chapters present the basics of statistical distributions, estimation, hypothesis testing, ANOVA, and experimental design. What that leaves for the statistician is the three-chapter primer on microarrays and image processing, plus all of the data analysis tools specific to the microarray situation. ! it includes two CDs with trial versions of several specialised software packages. Anyone who uses microarray data should certainly own a copy."
