का आवरण Gilberto Levy & Bruce Levin: The Biostatistics of Aging (ePUB)
A practical and clarifying approach to aging and
aging-related diseases

Providing a thorough and extensive theoretical framework, The
Biostatistics of Aging: From Gompertzian Mortality to an Index of
Aging-Relatedness addresses the surprisingly
subtlenotion–with consequential biomedical and public health
relevance–of what it means for acondition to be related to
aging. In this pursuit, the book presents a new quantitative
methodto examine the relative contributions of genetic and
environmental factors to mortality anddisease incidence in a
population.

With input from evolutionary biology, population genetics,
demography, and epidemiology, this medically motivated book
describes an index of aging-relatedness and also features:

* Original results on the asymptotic behavior of the minimum of
time-to-event random variables, which extends those of the
classical statistical theory of extreme values

* A comprehensive and satisfactory explanation based on
biological principles of the Gompertz pattern of mortality in human
populations

* The development of an evolution-based model of causation
relevant to mortality and aging-related diseases of complex
etiology

* An explanation of how and why the description of human
mortality by the Gompertz distribution can be improved upon from
first principles

* The amply illustrated analysis of real-world data, including a
program for conducting the analysis written in the freely available
R statistical software

* Technical appendices including mathematical material as well as
an extensive and multidisciplinary bibliography on aging and
aging-related diseases

The Biostatistics of Aging: From Gompertzian Mortality to an
Index of Aging-Relatedness is an excellent resource for
practitioners and researchers with an interest in aging and
aging-related diseases from the fields of medicine, biology,
gerontology, biostatistics, epidemiology, demography, and public
health.

लेखक के बारे में

GILBERTO LEVY, MD, DRPH, is a neurologist
with a primary research interest in aging and aging-related
diseases, particularly dementia. He conducted clinical research
within the spheres of epidemiological studies and clinical trials
at Columbia University for more than ten years. Dr. Levy is the
author of over thirty journal articles and three book chapters.

BRUCE LEVIN, PHD, is Professor of
Biostatistics and past chair of the Department of Biostatistics in
the Mailman School of Public Health at Columbia University. A
Fellow of the American Statistical Association, his research
interests include sequential selection procedures and their use in
adaptive clinical trial designs. He is the coauthor (with J.L.
Fleiss and M.C. Paik) of Statistical Methods for Rates and
Proportions, Third Edition, published by Wiley.
