Accelerated Failure Time Model with Generalized Estimating
Equations
Description
This package features both rank-based estimates and least
square estimates to the Accelerated Failure Time (AFT) model.
For rank-based estimation, it provides approaches that include
the computationally efficient Gehan's weight and the general's
weight such as the logrank weight. For the least square
estimation, the estimating equation is solved with Generalized
Estimating Equations (GEE). Moreover, in multivariate cases,
the dependence working correlation structure can be specified
in GEE's setting.
