at market price from your favorite bookseller


This second edition (2012) of the Nondetects And Data Analysis textbook (1st ed. 2004) introduces and explains methods for analyzing and interpreting censored ("nondetect") data in the environmental sciences. Adapting survival analysis techniques from other fields, the book translates well-established methods from other disciplines into new solutions for environmental studies. It applies methods of survival analysis, including methods for interval-censored data to the interpretation of low-level contaminants in environmental sciences and occupational health. New to the second edition was a chapter on multivariate methods for censored data, the use of interval-censored methods (especially for "remarked data" between the detection and quantitation limits), and expanded coverage of graphical methods for censored data. The basis for our Nondetects And Data Analysis online course and webinars.
