Testing multiple outcomes in repeated measures designs.
This study investigates procedures for controlling the familywise error rate (FWR) when testing hypotheses about multiple, correlated outcome variables in repeated measures (RM) designs. A content analysis of RM research articles published in 4 psychology journals revealed that 3 quarters of studies tested hypotheses about 2 or more outcome variables. Several procedures originally proposed for ...
متن کاملHE Plots for Repeated Measures Designs
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 size and significance. These methods are implemented in the heplots for R (Fox, Friendly, and Monette 2009a) and SAS (Friendly 2006), and appl...
متن کاملModels of accuracy in repeated-measures designs
Accuracy is often analyzed using analysis of variance techniques in which the data are assumed to be normally distributed. However, accuracy data are discrete rather than continuous, and proportion correct are constrained to the range 0–1. Monte Carlo simulations are presented illustrating how this can lead to distortions in the pattern of means. An alternative is to analyze accuracy using logi...
متن کاملRunning head: REPEATED MEASURES Analyzing Repeated Measures Designs Using Univariate and Multivariate Methods: A Primer
The present paper presents similarities and differences between the univariate and the multivariate analysis of repeated measures designs. Both methods are illustrated by means of an example. When the data are analyzed using the univariate approach and the homogeneity assumption is violated, three correcting factors are presented. When the data are analyzed using the multivariate approach, the ...
متن کاملTrend-resistant repeated measurement Designs
The existence and non-existence of trend-resistant repeated measurement designs are investigated. Two families of efficient/optimal repeated measurement designs which are very popular among experimenters are shown to be trend-resistant or trend-resistant with respect to treatments.
