Details

If all arguments have null or missing values, the result is a null or missing value depending on whether you are in ANSI mode or SAS mode. For more information, see How FedSQL Processes Nulls and SAS Missing Values.
Otherwise, the result is the interquartile range of the non-null or nonmissing values. The formula for the interquartile range is the same as the one that is used in the Base SAS UNIVARIATE procedure. For more information, see Base SAS Procedures Guide: Statistical Procedures.
