<p>Internal functions for the YPmodelPhreg package.</p>

Provides covariate-adjusted comparison of two groups of right
censored data, where the binary group variable has separate short-term
and long-term effects on the hazard function, while effects of covariates
such as age, blood pressure, etc. are proportional on the hazard. The model
was studied in Yang and Prentice (2015) <doi:10.1002/sim.6453> and it extends
the two sample version of the short-term and long-term hazard ratio model
proposed in Yang and Prentice (2005) <doi:10.1093/biomet/92.1.1>. The model
extends the usual Cox proportional hazards model to allow more flexible
hazard ratio patterns, such as gradual onset of effect, diminishing effect,
and crossing hazard or survival functions. This package provides
the following: 1) point estimates and confidence intervals for model
parameters; 2) point estimate and confidence interval of the average hazard
ratio; and 3) plots of estimated hazard ratio function with point-wise and
simultaneous confidence bands.
