afttest: Model Diagnostics for Accelerated Failure Time Models
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.
