Regression Survival Analysis with

Dependent Censoring

In this chapter, we develop the methodology to study the GLB Act’s impact both
to the survival of insurance companies and to the acquisition transactions among
those companies. Under a framework of regression survival analysis, the proposed
method models both independent and dependent censoring, and takes covariates into
consideration.

Section 3.1 introduces the definition of events and censoring with our research
objective, and illustrates common concerns over dependent censoring and proposes a
solution. Section 3.2 explains the advantages of copula approach and describes the
selection process among candidate copula functions. Section 3.3 integrates the copula
approach into survival analysis. Section 3.4 presents a simulation study demonstrating
