内容説明

This title offers everything you need to master innovative statistical methods for interpreting and analyzing censored environmental data. Adapting survival analysis methods that have been successfully used in medical and industrial research, the author demonstrates their practical applications for studies of trace chemicals in air, water, soils, and biota. You'll quickly become proficient in these methods through the use of real-world examples that are solved using MINITAB[registered] Release 14 and other commonly used software packages.
