The R package AFTtools provides additional tools
to work with parametric survival models fitted by survival::survreg.
To select the most appropriate distribution for the model, several models with
different distributions can be fit with only one call of compare_PSMdist(). Parallel
computation can be used to fasten the model estimations. The result can be printed
as a nice table by show_comparison().
Population average predictions (survival and quantiles) from parametric survival
models with frailties can be made using predict_survreg(). Bootstrap confidence
intervals of the predictions are also provided.
The functions AFTplot(), CSRplot(), Iplot(), and NPplot() produce diagnostic
plots.
NPplot() depends on interval which requires the package Icens from Bioconductor.
