Longitudinal Functional Data Analysis [PDF]

open access: yesStat, 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.

Inverse regression for longitudinal data [PDF]

open access: yesThe Annals of Statistics, 2015
Sliced inverse regression (Duan and Li [Ann. Statist. 19 (1991) 505-530], Li [J. Amer. Statist. Assoc. 86 (1991) 316-342]) is an appealing dimension reduction method for regression models with multivariate covariates.

Linkage analysis of longitudinal data [PDF]

open access: goldBMC Genetics, 2003
Abstract Background We propose a statistical model for linkage analysis of the longitudinal data. The proposed model is a mixed model based on the new Haseman and Elston model and allows several random effects.

Ignorability for general longitudinal data [PDF]

open access: yesBiometrika, 2017
Likelihood factors that can be disregarded for inference are termed ignorable. We demonstrate that close ties exist between ignorability and identification of causal effects by covariate adjustment. A graphical condition, stability, plays a role analogous to that of missingness at random, but is applicable to general longitudinal data.

Measurement in Intensive Longitudinal Data

open access: yesStructural Equation Modeling: A Multidisciplinary Journal, 2021
Technological advances have increased the prevalence of intensive longitudinal data as well as statistical techniques appropriate for these data, such as dynamic structural equation modeling (DSEM). Intensive longitudinal designs often investigate constructs related to affect or mood and do so with multiple item scales.
