This book introduces readers to advanced statistical methods for
analyzing survival data involving correlated endpoints. In particular,
it describes statistical methods for applying Cox regression to two
correlated endpoints by accounting for dependence between the endpoints
with the aid of copulas. The practical advantages of employing
copula-based models in medical research are explained on the basis of
case studies.
In addition, the book focuses on clustered survival data, especially
data arising from meta-analysis and multicenter analysis. Consequently,
the statistical approaches presented here employ a frailty term for
heterogeneity modeling. This brings the joint frailty-copula model,
which incorporates a frailty term and a copula, into a statistical
model. The book also discusses advanced techniques for dealing with
high-dimensional gene expressions and developing personalized dynamic
prediction tools under the joint frailty-copula model.
To help readers apply the statistical methods to real-world data, the
book provides case studies using the authors' original R software
package (freely available in CRAN). The emphasis is on clinical survival
data, involving time-to-tumor progression and overall survival,
collected on cancer patients. Hence, the book offers an essential
reference guide for medical statisticians and provides researchers with
advanced, innovative statistical tools. The book also provides a concise
introduction to basic multivariate survival models.
