Spending Scarce Confirmatory PET Measurements: Target-Aligned Validation in A4/LEARN
Eliuvish Han Cui, Qiang Yang, Meredith Mengmeng Zhang
Anti-amyloid therapies and blood-based biomarkers are changing Alzheimer disease workups into a two-stage measurement workflow: screen broadly with cheaper information, then spend…
The Statistical Compass
Eliuvish Han Cui
This monograph develops probability and stochastic-process ideas as a translation language for statistics: from designed observations and data objects to targets, stability stateme…
Brownian Motion with a Pulse: A Biostatistician's Guide to Diffusions, Bridges, Functional PCA, and First-Passage Models
Eliuvish Han Cui
Brownian motion is a compact mathematical language for continuous-time uncertainty in biostatistics. This tutorial develops the process from construction and path properties to too…
From Risk Sets to Martingales: A Counting-Process Framework for Event-History Learning
Eliuvish Han Cui
Counting-process notation separates predictable risk-set information from observed event jumps through decompositions of the form dN(t)=Y(t)alpha(t)dt+dM(t). This article develops…
