About this task
In the example below, you want to create nominal correlation analysis to compute
the minimal and maximal birth dates for each listed country in the selected nominal
column. Two columns are used for the analysis: birthdate and country.
Note: The nominal
correlation analysis is possible only on database columns for the time being. You
can not use this analysis on file connections.
