The authority on building empirical models and the fitting of suchsurfaces to data?completely updated and revised

Revising and updating a volume that represents the essentialsource on building empirical models, George Box and NormanDraper?renowned authorities in this field?continue toset the standard with the Second Edition of Response Surfaces,Mixtures, and Ridge Analyses, providing timely new techniques, newexercises, and expanded material.

A comprehensive introduction to building empirical models, thisbook presents the general philosophy and computational details of anumber of important topics, including factorial designs at twolevels; fitting first and second-order models; adequacy ofestimation and the use of transformation; and occurrence andelucidation of ridge systems.

Substantially rewritten, the Second Edition reflects theemergence of ridge analysis of second-order response surfaces as avery practical tool that can be easily applied in a variety ofcircumstances. This unique, fully developed coverage of ridgeanalysis?a technique for exploring quadratic responsesurfaces including surfaces in the space of mixture ingredientsand/or subject to linear restrictions?includes MINITAB®routines for performing the calculations for any number ofdimensions.

Many additional figures are included in the new edition, and newexercises (many based on data from published papers) offer insightinto the methods used. The exercises and their solutions provide avariety of supplementary examples of response surface use, formingan extremely important component of the text.

Response Surfaces, Mixtures, and Ridge Analyses, Second Editionpresents material in a logical and understandable arrangement andincludes six new chapters covering an up-to-date presentation ofstandard ridge analysis (without restrictions); design and analysisof mixtures experiments; ridge analysis methods when there arelinear restrictions in the experimental space including themixtures experiments case, with or without further linearrestrictions; and canonical reduction of second-order responsesurfaces in the foregoing general case.

Additional features in the new edition include:

• New exercises with worked answers added throughout
• An extensive revision of Chapter 5: Blocking and Fractionating2k Designs
• Additional discussion on the projection of two-level designsinto lower dimensional spaces

This is an ideal reference for researchers as well as a primarytext for Response Surface Methodology graduate-level courses and asupplementary text for Design of Experiments courses at theupper-undergraduate and beginning-graduate levels.
