 *  @brief Contains tests for psVectorStats with sample mean calculations
 *
-*  @author George Gusciora, MHPCC
+*  We extensively test the code with data type PS_TYPE_F32.  If these pass, we 
+*  do a much simpler test with data types PS_TYPE_U8, PS_TYPE_U16, PS_TYPE_F64.
+*
+*  If the psStats,c code every changes such that vectors of different type
+*  are handled by different routines, then these tests must be extended.
