Quantile Regression to Detect Subtle Cognitive Decline Lead Investigator: Lan Wang Institution : University of Minnesota E-Mail : wangx346@umn.edu Proposal ID : 303 Proposal Description: Our research goal is to use quantile regression technique to define a method to help detect subtle cognitive decline. We'll provide an estimate of the percentile range of a given individual's performance for each of the neuropsychological tests based on gender, age, education and other variables, using the cognitively normal subjects from the UDS data as baseline.
