The Short-Term and Long-Term Hazard Ratio Model for Survival Data
// Inference procedures accommodate a flexible range of hazard
ratio patterns with a two-sample semi-parametric model. This
model contains the proportional hazards model and the
proportional odds model as sub-models, and accommodates non-
proportional hazards situations to the extreme of having
crossing hazards and crossing survivor functions. Overall, this
package has four major functions: 1) the parameter estimation,
namely short-term and long-term hazard ratio parameters; 2) 95
percent and 90 percent point-wise confidence intervals and
simultaneous confidence bands for the hazard ratio function; 3)
p-value of the adaptive weighted log-rank test; 4) p-values of
two lack-of-fit tests for the model. See the included
"read_me_first.pdf" for brief instructions. In this version
(1.1), there is no need to sort the data before applying this
package.
