Conservative Sample Size Determination for Repeated Measures Analysis of Covariance.
In the design of a randomized clinical trial with one pre and multiple post randomized assessments of the outcome variable, one needs to account for the repeated measures in determining the appropriate sample size. Unfortunately, one seldom has a good estimate of the variance of the outcome measure, let alone the correlations among the measurements over time. We show how sample sizes can be cal...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Meaningful Statistical Model Formulations for Repeated Measures
When choosing a parametric statistical model two important considerations are mathematical soundness and substantive relevance. In this paper, we illustrate and exemplify that a number of issues arise from these considerations, even in relatively simple settings, such as ordinal regression, linear mixed models, models for cross-classified data and generalized linear mixed models. Many of our po...
متن کاملConfidence regions for repeated measures ANOVA power curves based on estimated covariance
BACKGROUND Using covariance or mean estimates from previous data introduces randomness into each power value in a power curve. Creating confidence intervals about the power estimates improves study planning by allowing scientists to account for the uncertainty in the power estimates. Driving examples arise in many imaging applications. METHODS We use both analytical and Monte Carlo simulation...
متن کاملModels for the Covariance Matrix of Multivariate Longitudinal and Repeated Measures Data
We present flexible, fully Bayesian models for the covariance structure of unbalanced multivariate repeated measures data. A typical setting involves measurements on many subjects taken at any of a large number of possible times. Unstructured covariance matrices have too many parameters to be fit to this sort of data, so researchers have typically relied on structured covariance matrices which ...
