Quizplus · Accepted Answer

Discriminant analysis is specifically designed for classification tasks where the observations are grouped into predefined classes. This technique builds a model based on the differences between the classes and then uses that model to classify new observations into one of the classes. Logistic regression, linear regression, and k-Nearest Neighbors algorithm can be used for classification, but they are also commonly used for other types of data analysis tasks.
