MULTISTAGE EVALUATION OF MEASUREMENT ERROR IN A RELIABILITY STUDY

by

Aiyi Liu
NICHD


Abstract

We introduce sequential testing procedures for the planning and analysis of reliability studies to assess an exposure's measurement error. The designs allow repeated evaluation of reliability of the measurements and stop testing if early evidence shows the measurement error is within the level of tolerance. Methods are developed and critical values tabulated for a number of two-stage designs. The methods are exemplified using an example evaluating the reliability of biomarkers associated with oxidative stress.
