Andrew Tredennick, Ph.D.

Senior Scientist II

Andrew joined MetrumRG in September 2022 as a Research Scientist. He earned his PhD in Ecology from Colorado State University, followed by a National Science Foundation Postdoctoral Research Fellowship in Biology and Mathematics at Utah State University. Nearly all of Andrew’s work relies on confronting mechanistic models with data to make predictions and inference. His interest in fitting dynamical models to data led to a postdoctoral appointment at the University of Georgia’s Center for the Ecology of Infectious Diseases. Andrew then worked for four years as a statistical consultant in the environmental space before joining MetrumRG. Andrew has completed projects on early warning signals for disease re-emergence and forecasting models of emerging infectious diseases, like COVID-19.

Gompertz Cure Rate Survival Models with Stan and brms.

December 6, 2024

Presented at ACoP 2024. A Gompertz distribution is implemented in Stan and brms to enable cure rate survival modeling. The Gompertz brms family can be used to model exposure-response data in a Bayesian framework where a proportion of the population never experiences the event of interest.
