QDA is the generalization of a common technique such as quadratic regression. It is simply a generalization of a model to allow for more complex models to fit, though, like all things, when allowing complexity to creep in, we make our lives more difficult.
Working with QDA – a nonlinear LDA
Getting ready
We will expand on the last recipe and look at QDA via the QDA object.
We said we made an assumption about the covariance of the model. Here we will relax that assumption.
How to do it...
- QDA is aptly a member of the qda module. Use the following commands to use...
