 * Strategies for handling NaN values in rank transformations.
 * <ul>
 * <li>MINIMAL - NaNs are treated as minimal in the ordering, equivalent to
 * (that is, tied with) <code>Double.NEGATIVE_INFINITY.
 * <li>MAXIMAL - NaNs are treated as maximal in the ordering, equivalent to
 * <li>REMOVED - NaNs are removed before the rank transform is applied
 * <li>FIXED - NaNs are left "in place," that is the rank transformation is
 * applied to the other elements in the input array, but the NaN elements
 * are returned unchanged.</li>
 * <li>FAILED - If any NaN is encountered in the input array, an appropriate
 * exception is thrown</li>
