Outcomes of the Health Data Research Network (HDRN) Canada and Canadian Longitudinal Study on Aging (CLSA) Partnership

open access: yesInternational Journal of Population Data Science
Objective and Approach The Canadian Longitudinal Study on Aging (CLSA) is the largest national longitudinal cohort study, following ~50,000 adults across 10 provinces for at least 20 years. Health Data Research Network (HDRN) Canada is a distributed pan-

Longitudinal Functional Data Analysis

open access: yes, 2015
We consider analysis of dependent functional data that are correlated because of a longitudinal-based design: each subject is observed at repeated time visits and for each visit we record a functional variable.

Modeling left-truncated and right-censored survival data with longitudinal covariates [PDF]

open access: yes, 2012
There is a surge in medical follow-up studies that include longitudinal covariates in the modeling of survival data. So far, the focus has been largely on right-censored survival data.

Predictive utility of key family planning indicators on dynamic contraceptive outcomes: Results from longitudinal surveys in Burkina Faso, Kenya, Uganda, and Côte d'Ivoire [PDF]

open access: yesDemographic Research
BACKGROUND: Many health and demographic surveys routinely collect information on women’s exposure to family planning (FP) messages, counseling on contraceptive side effects, discussions about FP with providers, contraceptive decision-making autonomy, and

Estimating correlation between multivariate longitudinal data in the presence of heterogeneity [PDF]

open access: yes, 2017
Background Estimating correlation coefficients among outcomes is one of the most important analytical tasks in epidemiological and clinical research. Availability of multivariate longitudinal data presents a unique opportunity to assess joint evolution ...

Longitudinal Scalar-on-Function Regression with Application to Tractography Data [PDF]

open access: yes, 2012
We propose a class of estimation techniques for scalar-on-function regression in longitudinal studies where both outcomes, such as test results on motor functions, and functional predictors, such as brain images, may be observed at multiple visits.

Functional single index models for longitudinal data

open access: yes, 2011
A new single-index model that reflects the time-dynamic effects of the single index is proposed for longitudinal and functional response data, possibly measured with errors, for both longitudinal and time-invariant covariates.

A Novel Joint Brain Network Analysis Using Longitudinal Alzheimer's Disease Data. [PDF]

open access: yes, 2019
There is well-documented evidence of brain network differences between individuals with Alzheimer's disease (AD) and healthy controls (HC). To date, imaging studies investigating brain networks in these populations have typically been cross-sectional ...
