  "Description": "Implements several basic algorithms for estimating\nregression parameters for semiparametric accelerated failure\ntime (AFT) model. The main methods are: Jin rank-based method\n(Jin (2003) <doi:10.1093/biomet/90.2.341>), Heller’s estimating\nmethod (Heller (2012) <doi:10.1198/016214506000001257>),\nPolynomial smoothed Gehan function method (Chung (2013)\n<doi:10.1007/s11222-012-9333-9>), Buckley-James method (Buckley\n(1979) <doi:10.2307/2335161>) and Jin`s improved least squares\nmethod (Jin (2006) <doi:10.1093/biomet/93.1.147>). This package\ncan be used for modeling right-censored data and for comparing\ndifferent estimation algorithms.",
