Computing for Unbalanced Repeated Measures Experiments
Repeated measures experiments involve two or more intended measurements per subject. If the within-subjects design is the same for each subject, and if no data are missing, then the analysis is not very hard and there are readily available programs that do the analysis automatically. Huwever, if the data are not balanced, with the same arrangement for eaeh subject, then the analysis becomes muc...
متن کاملUsing the general linear mixed model to analyse unbalanced repeated measures and longitudinal data.
The general linear mixed model provides a useful approach for analysing a wide variety of data structures which practising statisticians often encounter. Two such data structures which can be problematic to analyse are unbalanced repeated measures data and longitudinal data. Owing to recent advances in methods and software, the mixed model analysis is now readily available to data analysts. The...
متن کاملSelecting the best measures to discover quantitative association rules
The majority of the existing techniques to mine association rules typically use the support and the confidence to evaluate the quality of the rules obtained. However, these two measures may not be sufficient to properly assess their quality due to some inherent drawbacks they present. A review of the literature reveals that there exist many measures to evaluate the quality of the rules, but tha...
متن کاملSelecting the Best Prediction Model for Readmission
OBJECTIVES This study aims to determine the risk factors predicting rehospitalization by comparing three models and selecting the most successful model. METHODS In order to predict the risk of rehospitalization within 28 days after discharge, 11 951 inpatients were recruited into this study between January and December 2009. Predictive models were constructed with three methods, logistic regr...
متن کاملSelecting a sample size for studies with repeated measures
Many researchers favor repeated measures designs because they allow the detection of within-person change over time and typically have higher statistical power than cross-sectional designs. However, the plethora of inputs needed for repeated measures designs can make sample size selection, a critical step in designing a successful study, difficult. Using a dental pain study as a driving example...
