Discover relationships
SPSS Categories' dimension reduction techniques enable you to go beyond unwieldy tables to clearly see relationships in your data using revealing perceptual maps and biplots. Perceptual maps are high-resolution summary charts that graphically display similar variables or categories close to each other. They provide you with unique insight into relationships between more than two categorical variables. Biplots enable you to look at the relationships among cases, variables, and categories. For example, examine customers, brands, and characteristics.
Whatever types of categories you study-market segments, subcultures, political parties, or biological species-optimal scaling procedures free you from the restrictions associated with two-way tables, placing the relationships among your variables in a larger frame of reference.
