Analyzing Non-proportional Hazards: Use of the MRH Package
Yolanda Hagar, Vanja Dukic
In this manuscript we demonstrate the analysis of right-censored survival outcomes using the MRH package in R. The MRH package implements the multi-resolution hazard (MRH) model, w…
Models with time-varying predictors for meningitis in Navrongo, Ghana
Yolanda Hagar, Mary Hayden, Abudulai Adams Forgor +4
The "meningitis belt" is a region in sub-Saharan Africa where annual outbreaks of meningitis occur, with large epidemics observed cyclically. While we know that meningitis is heavi…
A Multivariate Cure Model for Left- and Right-Censored Data with Application to Colorectal Cancer Screening Patterns
Yolanda Hagar, Danielle Harvey, Laurel Beckett
We develop a multivariate cure survival model to estimate lifetime patterns of colorectal cancer screening. Screening data cover long periods of time, with sparse observations for…
Comparison of hazard rate estimation in R
Yolanda Hagar, Vanja Dukic
We give an overview of eight different software packages and functions available in R for semi- or non-parametric estimation of the hazard rate for right-censored survival data. Of…
Modeling Long-term Outcomes and Treatment Effects After Androgen Deprivation Therapy for Prostate Cancer
Yolanda Hagar, James J. Dignam, Vanja Dukic
Analyzing outcomes in long-term cancer survivor studies can be complex. The effects of predictors on the failure process may be difficult to assess over longer periods of time, as…
