PartitionFieldStats
class PartitionFieldStats(val field: Field, val frequencies: Array[Double], val weighted: Boolean, val counts: Option[Counts], val numericInfo: Option[NumericInfo], val sumValues: Option[Array[Double]], val sumSquaredValues: Option[Array[Double]]) extends PmmlElement
field references to (the name of) a MiningField for background statistics. The sequence of NUM-ARRAYs is the same as for ContStats. For categorical fields there is only one array containing the frequencies; for numeric fields, the second and third array contain the sums of values and the sums of squared values, respectively. The number of values in each array must match the number of categories or intervals in UnivariateStats of the field.
