In this course a variety of multivariate analysis models will be discussed. Prior to the selection of the appropriate model some common problems will be dealt with. For instance: how to check assumptions, what to do if assumptions are wrong, how to deal with missing data, what to do with outliers? Furthermore: are relationships between variables linear or not? Are variables normally distributed and does transformation of the variables lead to more optimal statistical tests? Besides this “cleaning up” the data, selection of the appropriate model plays an important role in this course. Related to this model selection measures of effect size will be discussed. Models which will be discussed are: Multiple regression analysis, multivariate analysis of variances and covariances, discriminant analysis, profile analysis, survival analysis.
Most statistical analyses will be carried out by the computer package SPSS, however, for those cases in which SPSS doesn’t have the proper model available, computations will be carried out by the package R.
