Use the OneWayAnovaModel to represent an analysis of variance model
with one factor. The dependent variable and factor variable must be specified in the constructor.
The dependent variable must be numerical. The factor variable
must be categorical.
OneWayAnovaModel inherits from AnovaModel, which in turn inherits
from AnovaModel. All methods and properties of these classes are available.
Before you can access the results of the analysis, you must call the Fit
method.
The results of the analysis are available through properties of the model object, including
FStatistic and PValue. They are summarized in the
AnovaTable.
The Cells property returns a vector of Cell objects
that represents the data organized into cells. There is one cell
for every combination of factor levels. Cell means and other
properties of the model can be accessed through the properties of individual cells.
One of the assumptions in analysis of variance is that the variances of the data in each cell are
the same. The GetHomogeneityOfVariancesTest returns a hypothesis test object
that allows you to verify this assumption.
