Brief Overview of Manova Page 1 Brief Overview of Manova In this and other handouts , we’ll briefly go over some advanced techniques that can be useful when estimating complicated models. We won’t discuss these in detail, but at least you’ll know what to look up should you encounter such problems in your research. M ULTIPLE DEPENDENT VARIABLES : M ANOVA . We are often interested in models such as the following: Y1 u X Y2 v Y3 w In this model, there are multiple dependent variables. The IV, X, affects each of them. However, their residuals are also correlated, presumably because of the influence of other variables omitted from the model. The disturbances are connected to each other by two-sided arrows because they are assumed to be correlated, but without a specification of which disturbance is a cause and which is an effect of the others. A common situation in which this occurs is when X is a “treatment” variable, and is coded 0 -1 (subject is or is not a member of the treatment group). Why might we want to have more than one dependent variable? In many cases, researchers are not interested in a single measure of group differences. Rather, there are often several components, constructs or behaviors that might be affected by the treatment or that are useful to separate the groups.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
