Multivariate Longitudinal Analysis with Bivariate Correlation Test. [PDF]

open access: yesPLoS ONE, 2016
In the context of multivariate multilevel data analysis, this paper focuses on the multivariate linear mixed-effects model, including all the correlations between the random effects when the dimensional residual terms are assumed uncorrelated.

Bivariate association analysis of longitudinal phenotypes in families [PDF]

open access: goldBMC Proceedings, 2014
Statistical genetic methods incorporating temporal variation allow for greater understanding of genetic architecture and consistency of biological variation influencing development of complex diseases. This study proposes a bivariate association method jointly testing association of two quantitative phenotypic measures from different time points ...

Bivariate Analysis with Synthetic Hydrograph Shapes for Hydrological Dam Safety Assessment

open access: yesEnvironmental Sciences Proceedings, 2023
Hydrological dam safety analyses should assess the frequency curve of maximum reservoir water levels in flood events by routing a large set of inflow hydrographs. Therefore, stochastic bivariate analyses are used.

Bivariate sea-ice assimilation for global-ocean analysis–reanalysis [PDF]

open access: yesOcean Science, 2023
In the last decade, various satellite missions have been monitoring the status of the cryosphere and its evolution. Besides sea-ice concentration data, available since the 1980s, sea-ice thickness retrievals are now ready to be used in global operational

Analysis of bivariate flow karyotypes [PDF]

open access: yesCytometry, 1989
AbstractBivariate flow karyotype analysis is performed using data from chromosomes stained with two fluorescent dyes, typically chromomycin A3 and Hoechst‐33258, and measured in a flow cytometer or cell sorter (Carrano et al.: Proceedings of the National Academy of Sciences of the United States of America 76:1382–1384, 1979; Gray et al.: Proceedings of

Ride Comfort Analysis and Multivariable Co-Optimization of the Commercial Vehicle Based on an Improved Nonlinear Model

open access: yesIEEE Access, 2020
The performance of a suspension system is affected by the behavior and posture of its components. However, published studies usually conduct this research using the based-equivalent model without considering the characteristic curves or postures. In this

Interlimb Coordination: A New Order Parameter and a Marker of Fatigue During Quasi-Isometric Exercise?

open access: yesFrontiers in Physiology, 2021
Although exercise-induced fatigue has been mostly studied from a reductionist and component-dominant approach, some authors have started to test the general predictions of theories of self-organized change during exercises performed until exhaustion ...

Bivariate Flood Frequency Analysis Using Copulas

open access: yesProceedings, 2018
Flood frequency estimation for the design of hydraulic structures is usually performed as a univariate analysis of flood event magnitudes. However, recent studies show that for accurate return period estimation of the flood events, the dependence and the
