A collection of methods for both the rankbased estimates and leastsquare estimates to the Accelerated Failure Time (AFT) model. For rankbased 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 rankbased estimation can be found in Chiou et al. (2014) <doi:10.1007/s1122201393882> and Chiou et al. (2015) <doi:10.1002/sim.6415>. For the leastsquare 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 leastsquares estimation can be found in Chiou et al. (2014) <doi:10.1007/s109850149292x>.
