A scoping review of statistical methods for the analysis of method comparison studies with repeated measurements of clinical data [PDF]

open access: yesBMC Medical Research Methodology
Background Method comparison studies are conducted to examine the level of agreement between two instruments measuring physiological continuous parameters. The inclusion of repeated measurements in such studies poses additional challenges.

Longitudinal individual predictions from irregular repeated measurements data [PDF]

open access: yesScientific Reports, 2023
Intensive longitudinal data can be used to explore important associations and patterns between various types of inputs and outcomes. Nonlinear relations and irregular measurement occasions can pose problems to develop an accurate model for these kinds of

Association of handgrip strength with semen characteristics: a study with repeated measurements among healthy Chinese men [PDF]

open access: yesAsian Journal of Andrology, 2022
Accumulating epidemiological evidence shows that handgrip strength provides predictive potential in physical, mental, and reproductive health status. However, the associations between handgrip strength and semen characteristics have not been explored. We

The analysis of very small samples of repeated measurements II: a modified box correction [PDF]

open access: yes, 2010
There is a need for appropriate methods for the analysis of very small samples of continuous repeated measurements. A key feature of such analyses is the role played by the covariance matrix of the repeated observations.

Observer-based H∞ control for systems with repeated scalar nonlinearities and multiple packet losses [PDF]

open access: yes, 2009
This paper is concerned with the H∞ control problem for a class of systems with repeated scalar nonlinearities and multiple missing measurements. The nonlinear system is described by a discrete-time state equation involving a repeated scalar nonlinearity,

Springer: An R package for bi-level variable selection of high-dimensional longitudinal data

open access: yesFrontiers in Genetics, 2023
In high-dimensional data analysis, the bi-level (or the sparse group) variable selection can simultaneously conduct penalization on the group level and within groups, which has been developed for continuous, binary, and survival responses in the ...

Discriminant analysis for repeated measures data: a review

open access: yesFrontiers in Psychology, 2010
Discriminant analysis (DA) encompasses procedures for classifying observations into groups (i.e., predictive discriminative analysis) and describing the relative importance of variables for distinguishing amongst groups (i.e., descriptive discriminative ...

Prognostic value of temporal patterns of global longitudinal strain in patients with chronic heart failure

open access: yesFrontiers in Cardiovascular Medicine, 2023
BackgroundWe investigated whether repeatedly measured global longitudinal strain (GLS) has incremental prognostic value over repeatedly measured left ventricular ejection fraction (LVEF) and N-terminal pro B-type natriuretic peptide (NT-proBNP), and a ...
