DF = e 1 + e 2 - e 0 - 2

in Quantum/Quanvert:

DF = e 1 + e 2 - e 0 - 1

▪Use the property:

TOM.Statistics["ColumnProportions"].UseQFormula = True

▪Use the Use Quantum/Quanvert column proportions formula option that is available from the popup box in the Statistics tab of the Table Properties dialog.
