Accelerated Failure Time Model with Generalized Estimating
A collection of methods for both the 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.
Details of the rank-based estimation can be found in
Chiou et al. (2014) <10.1007> and
Chiou et al. (2015) <10.1002>.
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.
Details on the least-squares estimation can be found in
