Details

If all arguments have missing or null values, the result is a missing or null value. Otherwise, the result is the median absolute deviation from the median of the nonmissing or non-null values. The formula for the median is the same as the one that is used in the UNIVARIATE procedure. For more information, see Base SAS Procedures Guide: Statistical Procedures.
