Bayesian Nonparametric Causal Inference for Quantile Residual Life: An Application to Alzheimer's Disease
Woojung Bae, Taekwon Hong, Sang Kyu Lee +2
In Alzheimer's disease research, a clinically important question is how much longer individuals would remain dementia-free beyond a given time under different baseline amyloid stat…
A Causal Framework for Quantile Residual Lifetime
Taekwon Hong, Woojung Bae, Sang Kyu Lee +2
Estimating prognosis conditional on surviving an initial high-risk period is crucial in clinical research. Yet, standard metrics such as hazard ratios are often difficult to interp…
Diagnostics for Semiparametric Accelerated Failure Time Models with R Package afttest
Woojung Bae, Dongrak Choi, Jun Yan +1
The semiparametric accelerated failure time (AFT) model offers a direct and interpretable alternative to the Cox proportional hazards model, yet practical diagnostic tools for this…
A general model-checking procedure for semiparametric accelerated failure time models
Dongrak Choi, Woojung Bae, Jun Yan +1
We propose a set of goodness-of-fit tests for the semiparametric accelerated failure time (AFT) model, including an omnibus test, a link function test, and a functional form test.…
