ANOVAFactorialGetTestEffects Method
Returns statistics relating to the sums of squares for the effects in the model. Note that the Compute method must be invoked first before invoking this method. Otherwise, the method throws a NullReferenceException exception.

Namespace: Imsl.Stat
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
Syntax
public double[,] GetTestEffects()

Return Value

Type: Double
A double matrix containing statistics relating to the sums of squares for the effects in the model.
Remarks
Here,

{\rm NEF} = {n \choose 1} + {n \choose 2} +
            \cdots + {n \choose \min(n,|{\rm model\_order}|)}

where n is given by nSubscripts if ANOVAFactorial.ErrorCalculation.Pooled is specified; otherwise, nSubscripts-1. Suppose the factors are A, B, C, and error. With ModelOrder = 3, rows 0 through NEF-1 would correspond to A, B, C, AB, AC, BC, and ABC, respectively.

The columns of the output matrix are as follows:
