Carmen D. Tekwe, Mercy Oladuti, Yuanyuan Luan +5
Digital health measures increasingly inform treatment evaluation, risk classification, clinical monitoring, and regulatory decisions. Existing validity concepts concern a measure's…
A Bayesian Functional Accelerated Failure-Time Model with Varying Effects Correcting for Measurement Error
Joseph Yang, Roger Zoh, Carmen Tekwe +1
Functional data collected as continuously observed trajectories arise naturally in many biomedical settings, and a key inferential goal is understanding how such functional covaria…
Correcting Measurement Error and Zero Inflation in Functional Covariates for Scalar-on-Function Quantile Regression
Caihong Qin, Lan Xue, Ufuk Beyaztas +4
Wearable devices collect time-varying biobehavioral data, offering opportunities to investigate how behaviors influence health outcomes. However, these data often contain measureme…
Estimating the effect of lymphovascular invasion on 2-year survival probability under endogeneity: a recursive copula-based approach
Yang Ou, Lan Xue, Carmen Tekwe +2
Lymphovascular invasion (LVI) is an important prognostic marker for head and neck squamous cell carcinoma (HNSC), but the true effect of LVI on survival may be distorted by endogen…
