Regression Analysis:concepts+appl.

This text focuses on how to solve practical statistical problems. The authors guide students from the theoretical (conceptual not mathematical) to the applied -- the idea being that samples (theory) tell the investigator what needs to be known about populations (application). Assumptions required to justify the validity of each technique are consistently stated. Chapters 6 and 7 present a broad range of applications, such as tolerance intervals, calibration, regulation, intersection of lines, variable selection, growth curves, and numerous others not generally covered by books at this level. A Data Disk features all data sets in the book plus macros which can be used with Minitab "RM" or SAS for solving problems.Graybill, Franklin A. is the author of 'Regression Analysis:concepts+appl.' with ISBN 9780534198695 and ISBN 0534198694.
