Multiple Imputation of Missing Data Using Stata

imputation model should always include all the variables in the analysis model, including the dependent variable of the analytic model as well as any other variables that may provide information about the probability of missigness, or about the true value of the missing data. Theory should guide the decision as to which variables to include.

A BRIEF INTRODUCTION TO MULTIVARIATE ANALYSIS OF …

As with ANOVA, the independent variables for a MANOVA are factors, and each factor has two or more levels. Unlike ANOVA, MANOVA includes multiple dependent variables rather than a single dependent variable. MANOVA evaluates whether the population means on a set of dependent variables vary across the levels of a factor or factors.

Now that our variables have been defined, we are almost ready to run the ANOVA. But before we do, we need to ask SPSS to produce some other information for us, to help us understand our data. First, we need to tell SPSS which descriptive and inferential statistics we want it to produce. CLICK on the Options button to do this.
