ABSTRACT

Throughout this book, analyses are illustrated using various example data sets. Data sets are chosen for particular scenarios to match data characteristics with the points and principles to be illustrated. A “hand-sized” data set of four subjects is used primarily in Chapter 5 to illustrate the mixed model equations to be solved for various longitudinal models. “Small” data sets of 50 subjects (25 per arm) with three post-baseline assessments are used to illustrate the actual implementations of those analyses. Two “large” data sets are used to illustrate the analyses in real settings, one where the rate of missing data was low and one where it was high. The following sections provide more details on each data set and how they were created.
