I fetched the code off the IXORA website, and I believe it can give erroneos results. The line which begin

          ratio_to_report(count(*))...

should be changed to

          ratio_to_report(count(&ColumnName)) ....

Ohrerwise if the distribution of values in the column is uniform with the exception of a great many nulls, then the distribution of values will be reported as skewed with one popular value.
