Abstract

Even though the logistic regression model is a very powerful classification tool, there are instances where the parameter estimates of these models become unstable. For example: when the classes are well-separated, and in instances where the sample size is small. Amongst the alternatives to these problems, Linear Discriminant Analysis (LDA) is popular especially when we have more than two response classes. Discriminant analysis allows for predicting group membership based on a set of continuous independent variables. It assumes that group membership is mutually exclusive and that the predictor variables are independent. Some extensions of the LDA will be discussed and some results will be demonstrated using MASS package R.
