Sequential Analysis

"...a reasonably comprehensive introduction to the topic, with an extensive bibliography to help those readers who wish to pursue further reading. The coverage of research literature is impressively up to date. The derivations of statistical models and procedures are generally very clear and technically sound. I particularly like the authors' approach to data analysis, which stresses working within a framework provided by substantive theory rather than testing parametric variations of a model....To those researchers whose substantive research questions are leading them into the new territory of sequential analysis, I recommend this book. A careful reading will help most invesigators gain the skills necessary to begin applying sequential analysis, and will point them in the right direction for gaining additional expertise." Linda M. Collins, Merrill-Palmer Quarterly
"...the reader who is interested in exploring sequential analysis can do no better than to begin with this book..." Dennis Delprato, The Psychological Record
