1351859 - Correlation() in Crystal Reports

What does the Correlation () function do in Crystal Reports

Enables you to calculate the correlation of the specified fields (that is, the degree to which the fields vary in the same manner). For example:

• You can calculate the correlation of two fields, for all the records in the report.
• You can calculate the correlation of two fields for all values within a group (for example, sales grouped by the state that they come from).
• You can calculate the correlation of two fields for all the values within a group in which grouping is controlled by changes in a date or Boolean field (for example, sales grouped by the month in which they were made).
