He is a widely-published author and frequent presenter at conferences and has developed a number of successful short courses and tutorials.
"This book deals mostly with longitudinal clinical trial data,
but also with the related issue of imputing missing data. The book
is an excellent resource overall, as it is fairly comprehensive,
well referenced, and clear."
~Vance W. Berger, PhD, NIH/NCI/DCP/BRGAnalyzing
Longitudinal Clinical Trial Data provides, in a well
organized and small format, a fairly easy read that could be
helpful for both researchers analyzing longitudinal data collected
from clinical trials (or perhaps even observational studies) and
instructors teaching undergraduate and graduate courses on clinical
trials, longitudinal data, and missing data. The book is divided
into four well-structured and complementary sections: background
and setting, general modeling strategies and methods, methods for
dealing with missing data, and overall guidance (with illustration)
for developing a study.
~Journal of the American Statistical Association "I
recommend this book to anyone who deals with longitudinal clinical
trials data at any level with confidence as it concisely presents
essential ideas and analysis techniques with illustrative examples,
in an intuitively appealing way, both on analytic and conceptual
levels. It addresses an important need for practicing
(bio)statisticians."
~Biometrical Journal
