Discriminant and logistic regression analysis are statistical techniques that point out the differences between two or more groups based on several characteristics (most often rating scales when discriminant analysis, while logistic regression can handle any type of variable).It explains why respondents belong to a certain group, plus it classifies new respondents based on their ratings. Is often used:

• To determine which customers are likely to buy a company's product
• To decide whether a bank should offer a loan to a new company or
• To identify patients which may be at high risk for medical problems
