A collection of model checking methods for semiparametric
accelerated failure time (AFT) models under the rank-based approach. For the
(computational) efficiency, Gehan's weight is used. It provides functions to
verify whether the observed data fit the specific model assumptions such as
a functional form of each covariate, a link function, and an omnibus test.
The p-value offered in this package is based on the Kolmogorov-type supremum
test and the variance of the proposed test statistics is estimated through
the re-sampling method. Furthermore, a graphical technique to compare the
shape of the observed residual to a number of the approximated realizations
is provided. See the following references; A general model-checking
procedure for semiparametric accelerated failure time models, Statistics and
Computing, 34 (3), 117 <doi:10.1007/s11222-024-10431-7>; Diagnostics for
semiparametric accelerated failure time models with R package 'afttest',
