aftgee: Accelerated Failure Time Model with Generalized Estimating
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.
