<DD>Recalculates the attribute statistics for all attributes. They are
 average value, variance, minimum, and maximum. For nominal attributes the
 occurences for all values are counted. This method collects all
 attributes (regular and special) in a list and invokes
 <code>recalculateAttributeStatistics(List attributes)</code> and
 performs only one data scan.
