HE Plots for Repeated Measures Designs [PDF]

open access: yesJournal of Statistical Software, 2010
Hypothesis error (HE) plots, introduced in Friendly (2007), provide graphical methods to visualize hypothesis tests in multivariate linear models, by displaying hypothesis and error covariation as ellipsoids and providing visual representations of effect

Impact of Correlation between Multiple Time Point Measurements on Pooled Effect Measures in Meta-analysis [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2023
Introduction: Effect estimates obtained from multiple time points based on the same set of subjects are observed to be correlated. There is a need to integrate these correlations in the derivation of pooled summary measures to improve the precision of ...

Use of Repeated Measures Data Analysis for Field Trials with Annual and Perennial Crops

open access: yesPlants, 2022
Field studies conducted over time to collect any type of plant response to a set of treatments are often not treated as repeated measures data. The most used approaches for statistical analyses of this type of longitudinal data are based on separate ...

The assumption of sphericity in repeated-measures designs: What it means and what to do when it is violated [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2016
Violating the assumption of sphericity in repeated-measures analysis of variance leads to an inflated Type I error rate. The first portion of this article provides a thorough yet non-technical description of the sphericity assumption and explains why ...

Assessing the cardiac autonomic response to bicycle exercise in Olympic athletes with different loads of endurance training: new insights from statistical indicators based on multilevel exploratory factor analysis

open access: yesFrontiers in Physiology, 2023
Aim: The mechanisms governing the organism’s response to exercise are complex and difficult to study. Spectral analysis of heart rate variability (HRV) could represent a convenient methodology for studying humans’ autonomic nervous system (ANS). However,

The use of mixed models in a modified Iowa Gambling Task and a prisoner's dilemma game [PDF]

open access: yesJudgment and Decision Making, 2007
Researchers in the decision making tradition usually analyze multiple decisions within experiments by aggregating choices across individuals and using the individual subject as the unit of analysis.

Repeatability of fruit traits from two Hancornia speciosa populations from the core region of the Brazilian Cerrado [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2018
: The objective of this work was to estimate the repeatability coefficients of mangaba (Hancornia speciosa) fruit traits, in order to define the number of fruit needed for an accurate selection of superior genotypes, as well as to conjecture about the ...
