Include Automatically Combine Categories By Value Intro

The features in Automatically Combine Categories - By Value allow you to create categories from numeric data using one of server different rules. Each category contains a range of values. This is sometimes referred to as banding, binning, or aggregating.

There are four different methods available for combining numeric values in this tool:

• Tidy categories divides the range of values into tidy categories, which are intervals of 2, 5, 10, 20, 50, and so on.
• Percentiles divides the range up into percentiles. This is useful when you want to create categories which contain even proportions of the cases in your data.
• Equally spaced categories divides the range of values into categories that all have the same range. This is similar to Tidy categories, but has additional options for customization.
• Custom categories divides the range of values up into ranges of your choice. This is useful when you want to specify uneven ranges of values.
