Fit Additive Hazards Models for Survival Analysis

Contains tools to fit the additive hazards model to data from a cohort, random sampling, two-phase Bernoulli sampling and two-phase finite population sampling, as well as calibration tool to incorporate phase I auxiliary information into the two-phase data model fitting. This package provides regression parameter estimates and their model-based and robust standard errors. It also offers tools to make prediction of individual specific hazards.


addhazard 1.1.0 updates:

  1. add a two-phase sampling example dataset, nwts.2ph.rda, to the data folder
  2. add R file nwts.2ph.generator.R to generate the nwts.2ph example dataset
  3. update documentations
  4. add rownames to the summary stat where there is only one covariate
  5. clean the typo in ah.2ph() on updating wts.2ph
  6. add importFrom stats model.weight to ah.R file
  7. add ah.fit.R but currently surppress the use of this function. It will be activated in the later version.
