A Dataset is a wrapper for a collection of records that can be analyzed, in order to build or run a model.

Implementations abstracting different sources of data can be found in <package>DeepSee.PMML.Dataset</package>.

Clears all temporary structures created by this object.

The dataset should remain usable after calling this method!

Reimplemented in Table.

Get1DDistribution()

_.Library.Status Get1DDistribution	(	_.Library.String	pField,
			pDistribution,
			pFilters
	)

Returns an array describing the distribution of values for a field pField (categorical)

accepts pFilters(n) = $lb(field, operator, key) returns: pDistribution("total") = tTotalCount pDistribution(n) = $lb(value, count)

Reimplemented in Table, Cube, and Bootstrap.

GetAggregatesByCategory()

_.Library.Status GetAggregatesByCategory	(	_.Library.String	pContField,
		_.Library.String	pCatField,
			pAggregates,
			pFilters
	)

Returns an array listing aggregate values for a continuous field pContField for.

each value of a categorical field pCatField. accepts pFilters(n) = $lb(field, operator, key) returns: pAggregates("total") = tTotalCount pAggregates(n) = $lb(category value, count, average, sum, max, min, countNonNull)

Reimplemented in Table.

GetXDDistribution()

_.Library.Status GetXDDistribution	(	_.Library.List	pFields,
			pDistribution,
			pFilters
	)

accepts

pFilters(n) = $lb(field, operator, key) returns: pDistribution = $lb(dim1Count, dim2Count, ...) pDistribution("value", dim, i) = value pDistribution(i, j, ...) = tCount pDistribution("total", dim, i) = tDimTotal

Reimplemented in Table, Cube, and Bootstrap.
