Generalized Multilevel Functional Principal Component Analysis with Application to NHANES Active Inactive Patterns
Xinkai Zhou, Julia Wrobel, Ciprian M. Crainiceanu +1
Between 2011 and 2014 NHANES collected objectively measured physical activity data using wrist-worn accelerometers for tens of thousands of individuals for up to seven days. In thi…
Fast Generalized Functional Principal Components Analysis
Andrew Leroux, Ciprian Crainiceanu, Julia Wrobel
We propose a new fast generalized functional principal components analysis (fast-GFPCA) algorithm for dimension reduction of non-Gaussian functional data. The method consists of: (…
A case study of glucose levels during sleep using fast function on scalar regression inference
Renat Sergazinov, Andrew Leroux, Erjia Cui +4
Continuous glucose monitors (CGMs) are increasingly used to measure blood glucose levels and provide information about the treatment and management of diabetes. Our motivating stud…
Epidemiology of Objectively Measured Bedtime and Chronotype in the US adolescents and adults: NHANES 2003-2006
Jacek K. Urbanek, Adam Spira, Junrui Di +3
Background: We propose a method for estimating the timing of in-bed intervals using objective data in a large representative U.S. sample, and quantify the association between these…
