The mathematics of discriminant analysis are related very closely to the one- way MANOVA. In fact, the roles of the variables are simply reversed. The classification (factor) variab le in the MANOVA becomes the dependent variable in discriminant analysis. The dependent variables in the MANOVA become the independent variables in

As an example of multiple logistic regression, in the 1800s, many people tried to bring their favorite bird species to New Zealand, release them, and hope that they become established in nature. (We now realize that this is very bad for the native species, so if you were thinking about trying this, please don't.)
