This book provides an updated account of the regression techniques
employed in comparing analytical methods and to test the biases of one
method relative to others - a problem commonly found in fields like
analytical chemistry, biology, engineering, and medicine. Methods
comparison involves a non-standard regression problem; when a method is
to be tested in a laboratory, it may be used on samples of suitable
reference material, but frequently it is used with other methods on a
range of suitable materials whose concentration levels are not known
precisely. By presenting a sound statistical background not found in
other books for the type of problem addressed, this book complements and
extends topics discussed in the current literature. It highlights the
applications of the presented techniques with the support of computer
routines implemented using the R language, with examples worked out
step-by-step. This book is a valuable resource for applied
statisticians, practitioners, laboratory scientists, geostatisticians,
process engineers, geologists and graduate students.
