Example use of the NADA

SAS macro for Robust ROS.
Computes descriptive statistics (mean, etc) for censored data using
ROS. This macro correctly sets to missing all nondetects that are
higher than all detected values.
Robust ROS Standalone
program for Windows. NOTE: This standalone program incorrectly
handles nondetects higher than all detected values. These
nondetects should be ignored, but are not. Eliminate any nondetects
higher than all detects first before using this program. The NADA
for MTB and SAS macros correctly set these values to missing.
