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 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 ...
متن کاملModelling of Correlated Ordinal Responses, by Using Multivariate Skew Probit with Different Types of Variance Covariance Structures
In this paper, a multivariate fundamental skew probit (MFSP) model is used to model correlated ordinal responses which are constructed from the multivariate fundamental skew normal (MFSN) distribution originate to the greater flexibility of MFSN. To achieve an appropriate VC structure for reaching reliable statistical inferences, many types of variance covariance (VC) structures are considered ...
متن کامل199-30: Testing the Hypothesis of a Kroneckar Product Covariance Matrix in Multivariate Repeated Measures Data
We consider the problem of testing of a Kronecker product structured variance covariance matrix against the unstructured variance covariance matrix in the context of multivariate repeated measures data. A likelihood ratio test statistic is developed for this purpose. However, the test statistic for this test cannot be expressed in a closed form. An algorithm, is suggested for the maximum likeli...
