Goodness-of-Fit Methods for Additive-Risk Models in Tumorigenicity Experiments

Ghosh, Debashis - 2003

In tumorigenicity experiments, a complication is that the time to event is generally not observed, so that the time to tumor is subject to interval censoring. One of the goals in these studies is to properly model the effect of dose on risk. Thus, it is important to have goodness of fit...

Smooth Inference for Survival Functions with Arbitrarily Censored Data

Doehler, Kirsten Ann - 2006

We propose a new procedure for estimating the survival function of a time-to-event random variable under arbitrary patterns of censoring. Under mild smoothness assumptions, this procedure allows a unified approach to handling different kinds of censoring, while in many cases increasing...

Sexual Volatility and the Spread of HIV.

Romero-Severson, Ethan Obie - 2011

The stability of sexual risk behavior over time is a common assumption in models of HIV transmission. In this thesis I … show that this assumption does not hold in a population of gay men at risk of HIV infection and that the violation of this … assumption has major implications for our understanding of HIV transmission. Using multiple statistical models that assume either …

Ignoring ‘downstream infection’ in the evaluation of harm reduction interventions for injection drug users

Pollack, Harold A. - 2001

Harm reduction interventions to reduce blood-borne disease incidence among injection drug users (IDUs). A common strategy to estimate the long-term impact of such interventions is to examine short-term incidence changes within a specific group of individuals exposed to the intervention. Such...
