"Statistics" Page

Statistics page contains various statistical information about examined field and other fields values. The controls are filled automatically after processing the initial query.

Classes statistics

On this page you can view all Classes (unique values) met in the field selected for examination (view  "Query Parameters" page).

View number of records in wich values were found.

Fields Statistics

On this page you can view all values detected in fields, selected for initial statistics query. In case if the field was not selected for initial query, it wont' be available, and no field values will be displayed.

In the "Fields List" control values are grouped by fields and tables.

Each value is followed by the number of cases it was met in for every class.

Exceptions

On the exceptions page you can view the exceptions searching settings and the list of exceptions.

Exceptions searching options are set in the "Query Settings" dialog.

Exceptions give us understanding wich field values are not common for Classes.

In case if the option is turned off, or none of Classes has exceptions, the list will be empty. In other case, for each exeption there will be displayed a Class, a Field, and a value of the Field, wich can be considered as exception.

Field Values and Class

On this page you can view statistics of correlation between values in the examined field and other fields values.

For example, if some value wasn't met in any record for class, it will be displayed as "0" zero on the chart. In other case, there will be displayed a number of records, in wich the field value and the selected Class were met in.

This tab is very useful to view dependencies of fields you’ve analyzed to classes.  View how your data is distributed by classes and how field values can be helpful during rules and decision trees creation.  You can add fields and classes by double clicking them at the “Query parameters” tab in corresponding lists:
