<dd><p>Return asymmetry ratio measures based on Upper and Lower triangles. The ratios are calculated as <code>(upper - lower) / (upper + lower)</code>. So a value of 0 means no asymmetry, negative ratios indicate the measures based on the lower triangle had the higher values, positive ratios indicate measures based on the upper triangle had higher values (default = <code>FALSE</code>)</p></dd>
