summary.aftsem

Provides a summary of an aftsem model fit, including the model call,
residuals, initial and final coefficient estimates, method, convergence status,
number of iterations, number of observations, percent of censored observations,
and if available, the estimated covariance matrix of the coefficients, standard
deviations, z-values, and p-values for a Wald test.

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