SyntaxThe TwoWayAnova type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | TwoWayAnova | No argument contructor. Used primarily for serialization. |
 | TwoWayAnova(DataFrame, Int32, Int32, Int32) | Constructs a TwoWayAnova instance from data in the given data frame. |
Properties| Name | Description | |
|---|---|---|
 | AnovaTable | Gets a traditional two-way ANOVA table. |
| GrandMean |
Gets the grand mean.
(Overrides TwoWayAnovaBaseGrandMean) |
| RegressionFactorParameters | Gets the array of estimates for the linear regression parameters corresponding to the dummy variables for the different factor levels. |
| RegressionInteractionParameters | Gets the array of estimates for the linear regression parameters corresponding to the dummy variables for the interactions. |
| RegressionInterceptParameter |
Gets the intercept parameter from the linear regression that was used to
compute the ANOVA.
(Overrides TwoWayAnovaBaseRegressionInterceptParameter) |
Methods| Name | Description | |
|---|---|---|
| Clone | Creates a deep copy of this TwoWayAnova. |
| ComputeAnova | Compute the ANOVA for the given data. |
| ComputeFactorSumsOfSquares | Fill in the DoubleVector parameterSumsOfSquares_ with the sums of squares for the parameters used in the regression that is used to compute the ANOVA. |
| ComputeFactorSumsOfSquares(DoubleMatrix) |
Fill in the DoubleVector parameterSumsOfSquares_ with the sums of
squares for the parameters used in the regression that is used to
compute the ANOVA.
(Inherited from TwoWayAnovaBase) |
| ComputeFactorSumsOfSquares(LinearRegression, Int32, Int32, Int32) |
Fill in the DoubleVector parameterSumsOfSquares_ with the sums of
squares for the parameters used in the regression that is used to
compute the ANOVA.
(Inherited from TwoWayAnovaBase) |
| CreateAnovaTable | Create the ANOVA table for this object. |
| FillInRegressionMatrix | Fill in the regression matrix that is to be used for computing the ANOVA. |
| GetCellData |
Returns all the data in a cell, as defined by the levels of the two factors
in the ANOVA.
(Inherited from TwoWayAnovaBase) |
| GetMeanForCell |
Returns the mean for the specified cell, as defined by the levels of
the two factors in the ANOVA.
(Inherited from TwoWayAnovaBase) |
| GetMeanForFactorLevel |
Returns the mean for the specified factor level.

DoubleVector instance variable parameterSumsOfSquares with
the parameters for factor A first, followed by the parameters for
factor B and starting at the given index.
(Inherited from TwoWayAnovaBase) |
| MakeInteractionParameters(Int32) | Creates the array of AnovaRegressionInteractionParam objects using the DoubleVector instance variable parameterSumsOfSquares_. The sums of squares for the interaction parameters are assumed to begin at the given index. |
