Computer Programs:

BayesPieceHazSelect- R program for Bayesian variable selection on covariates in a cox-like hazard with a piecewise exponential baseline hazard.

BayesPiecewiseICAR – R program for fitting a piecewise exponential model to survival data.

SimSCRPiecewise – R program with two simulation functions, both with piecewise hazards.

  1. SimSCRPiecewise: Simulates data from a semi-competing risks model.
  2. SimUnivPiecewise: Simulates data from a piecewise constant hazard.

SCRSELECT – R programs for implementing the SVSS and DIC-Tau_g procedures from the paper:



I am currently a Ph.D. candidate in Biostatistics at Rice University, working with faculty at M.D.Anderson Cancer Center. My particular interests include: Clinical Trials, Bayesian Methods, Survival Analysis, Variable Selection, Categorical Data, Econometrics, and Teaching. I hope to improve on existing clinical trial methodology and use Bayesian methods for economic data to improve policy decisions.
