Summary

The much-anticipated ninth edition of this classic text/reference has been thoroughly updated. This new edition contains both the classic material you have counted on to drive home basic theory and points of reference; in addition, Dr. Koehler has added numerous new sections, figures and chapters to give students and professionals realistic data in which to learn from. Many previous chapters have been expanded. Just some of the new additions you will see in this new edition: Shapiro-Wilk and Kolmogorov-Smirnov tests for normality, expanded and more accurate approximation and discussion of sample size determination, and more accurate methods for constructing a confidence interval. Find new chapters on how to use logistic regression to model trends in proportions and how to apply Poisson regression models to count data. Another new chapter will introduce the exponential, log-normal and Weibull distributions, and discuss Kaplan-Meier estimators of survival curves and log-rank tests for comparing estimates of survival curves for several populations and much much more.
