Discriminant analysis is statistical technique used to classify observations into nonoverlapping groups, based on scores on one or more quantitative predictor variables. For example, a doctor could perform a discriminant analysis to identify patients at high or low risk for stroke.Discriminant analysis is a classification problem, where two or more groups or clusters or populations are known a priori and one or more new observations are classified into one of the known populations based on the measured characteristics. Let us look at three different examples. linear discriminant analysis excel example

Linear Discriminant Analysis (LDA) is a wellestablished machine learning technique and classification method for predicting categories. Its main advantages, compared to other classification algorithms such as neural networks and random forests, are that the model is interpretable and that prediction is easy. The posterior probability that is given by the formula. Example 1: Perform discriminant analysis on the data in Example 1 of MANOVA Basic Concepts. This data is repeated in Figure 1 (in two columns for easier readability).
