Praise for the First Edition
‘. . . an excellent textbook . . . an indispensable reference
for biostatisticians and epidemiologists.’
–International Statistical Institute
A new edition of the definitive guide to classical and modern
methods of biostatistics
Biostatistics consists of various quantitative techniques that
are essential to the description and evaluation of relationships
among biologic and medical phenomena. Biostatistical Methods:
The Assessment of Relative Risks, Second Edition develops basic
concepts and derives an expanded array of biostatistical methods
through the application of both classical statistical tools and
more modern likelihood-based theories. With its fluid and balanced
presentation, the book guides readers through the important
statistical methods for the assessment of absolute and relative
risks in epidemiologic studies and clinical trials with
categorical, count, and event-time data.
Presenting a broad scope of coverage and the latest research on
the topic, the author begins with categorical data analysis methods
for cross-sectional, prospective, and retrospective studies of
binary, polychotomous, and ordinal data. Subsequent chapters
present modern model-based approaches that include unconditional
and conditional logistic regression; Poisson and negative binomial
models for count data; and the analysis of event-time data
including the Cox proportional hazards model and its
generalizations. The book now includes an introduction to mixed
models with fixed and random effects as well as expanded methods
for evaluation of sample size and power. Additional new topics
featured in this Second Edition include:
* Establishing equivalence and non-inferiority
* Methods for the analysis of polychotomous and ordinal data,
including matched data and the Kappa agreement index
* Multinomial logistic for polychotomous data and proportional
odds models for ordinal data
* Negative binomial models for count data as an alternative to
the Poisson model
* GEE models for the analysis of longitudinal repeated measures
and multivariate observations
Throughout the book, SAS is utilized to illustrate applications
to numerous real-world examples and case studies. A related website
features all the data used in examples and problem sets along with
the author’s SAS routines.
Biostatistical Methods, Second Edition is an excellent
book for biostatistics courses at the graduate level. It is also an
invaluable reference for biostatisticians, applied statisticians,
and epidemiologists.
