Assessing the accuracy of predictive models with interval-censored data
Wu, Ying; Cook, Richard (Oxford University Press, 2022-01)We develop methods for assessing the predictive accuracy of a given event time model when the validation sample is comprised of case K interval-censored data. An imputation-based, an inverse probability weighted (IPW), and ... -
Modeling and Prediction of Disease Processes Subject to Intermittent Observation
Wu, Ying (University of Waterloo, 2016-07-21)This thesis is concerned with statistical modeling and prediction of disease processes subject to intermittent observation. Times of disease progression are interval-censored when progression status is only known at a ... -
Penalized Regression for Interval-Censored Times of Disease Progression: Selection of HLA Markers in Psoriatic Arthritis
Wu, Ying; Cook, Richard J. (Wiley, 2015-09)Times of disease progression are interval-censored when progression status is only known at a series of assessment times. This situation arises routinely in clinical trials and cohort studies when events of interest are ... -
A two-phase model for chronic disease processes under intermittent inspection
Wu, Ying; Cook, Richard J. (Wiley, 2017-06-15)A model is developed for chronic diseases with an indolent phase that is followed by a phase with more active disease resulting in progression and damage. The time scales for the intensity functions for the active phase ... -
Variable selection and prediction in biased samples with censored outcomes
Wu, Ying; Cook, Richard J. (Springer, 2018-01-01)With the increasing availability of large prospective disease registries, scientists studying the course of chronic conditions often have access to multiple data sources, with each source generated based on its own entry ...
