Degrees of freedom
in UNICOM Intelligence Professional:
DF = e 1 + e 2 - e 0 - 2
in Quantum/Quanvert:
DF = e 1 + e 2 - e 0 - 1
To reproduce the Quantum/Quanvert formula, do one of the following:
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.
