~c^!`median!
~wThe median is an alternative estimator for the rule.
The median is that value selected such that half of the prediction values ~
for the rows lie above the median and half lie below. ~
For sets of data that have large erratic noise values or other ~
non-normal behavior, the median is a better estimator than the average ~
given on the first line of the rule.
The low and high quartiles provide similar divisions of the row ~
predictions values that lie below and above the median, respectively.
