Namespace:  CenterSpace.NMath.Stats
Assembly:  NMathStats (in NMathStats.dll) Version: 3.4.0.0

Syntax

C#
public void SetData(
	DataFrame data,
	int groupColumn,
	int dataColumn,
	bool correct_for_ties
)
Visual Basic (Declaration)
Public Sub SetData ( _
	data As DataFrame, _
	groupColumn As Integer, _
	dataColumn As Integer, _
	correct_for_ties As Boolean _
)
Visual C++
public:
void SetData(
	DataFrame^ data, 
	int groupColumn, 
	int dataColumn, 
	bool correct_for_ties
)

Parameters

data
Type: CenterSpace.NMath.Stats..::.DataFrame
A DataFrame containing the data.
groupColumn
Type: System..::.Int32
The index of the DataFrame column containing the group values.
dataColumn
Type: System..::.Int32
The index of the DataFrame column containing the numeric data. The specified column must be of type DFNumericColumn.
correct_for_ties
Type: System..::.Boolean
If true, a standard correction for ties is applied. This correction usually makes little difference in the value of the test statistic unless there are a large number of ties.

Remarks

The DataFrame method GetGroupings() is applied to the specified group column, producing a sorted list of unique group values.
