"Simply superb! The novice will appreciate the gentle introduction to regression methods, while the more advanced readerwill find challenging topics including non-parametric smoothing, moving averages, spline fitting, response surface plots, and ridge regression presented in a concise, applied fashion. A perfect companion to classic regression texts such as Neter, Wasserman and Kutner, and Montgomery and Peck."
