  "description" : "Converts a multivalued field into a single valued field containing the median absolute deviation.\n\nIt is calculated as the median of each data point’s deviation from the median of the entire sample. That is, for a random variable `X`, the median absolute deviation is `median(|median(X) - X|)`.",
  "note" : "If the field has an even number of values, the medians will be calculated as the average of the middle two values. If the value is not a floating point number, the averages are rounded towards 0.",
