Returns the regression parameter associated with the specified factor level.

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

Syntax

C#
public AnovaRegressionFactorParam GetRegressionFactorParameter(
	string factorName,
	Object factorLevel
)
Visual Basic (Declaration)
Public Function GetRegressionFactorParameter ( _
	factorName As String, _
	factorLevel As Object _
) As AnovaRegressionFactorParam
Visual C++
public:
AnovaRegressionFactorParam^ GetRegressionFactorParameter(
	String^ factorName, 
	Object^ factorLevel
)

Parameters

factorName
Type: System..::.String
The name of a factor.
factorLevel
Type: System..::.Object
The level of the factor.

Return Value

Regression parameter information for the given factor level, if the specified factor level has a regression parameter associated with it; otherwise, null.

Remarks

To construct the linear regression used to compute the two way ANOVA, the effects encoding method is used for the dummy regression variables. This means that if a factor has n different levels there are n-1 dummy variables corresponding to that factor. Hence, one level does not have a dummy variable associated with it in the linear regression, and a null reference may be returned even though a valid factor level is specified.
