Methods​

GetValueCount​

Method GetValueCount(pField As %String, pIncludeNull As %Boolean = 1, ByRef pFilters, Output pSC As %Status) As %Integer [ Abstract ]

Returns the number of distinct values for pField (categorical)

Get1DDistribution​

Method Get1DDistribution(pField As %String, Output pDistribution, ByRef pFilters) As %Status [ Abstract ]
