Contrast
Saves variables called Canon[1], Canon[2], and so on, as columns in the
current data table. These columns have both the values and their formulas.
Performs the statistical contrasts of treatment levels that you specify in the
contrasts dialog.
Note: The Contrast command is the same as for regression with a single
response. See the “LSMeans Contrast” on page 110 in the “Fitting Standard
Least Squares Models” chapter, for a description and examples of the
LSMeans Contrast commands.
Example of Test Details (Canonical Details)
1. Open the Iris.jmp sample data table.
The Iris data (Mardia, Kent, and Bibby, 1979) have three levels of Species named Virginica, Setosa, and
Versicolor. There are four measures (Petal length, Petal width, Sepal length, and Sepal width) taken on
each sample.
2. Select Analyze > Fit Model.
3. Select Petal length, Petal width, Sepal length, and Sepal width and click Y.
4. Select Species and click Add.
5. For Personality, select Manova.
6. Click Run.
7. Click on the Choose Response button and select Identity.
8. Click Run.
9. From the red triangle menu next to Species, select Test Details.
The eigenvalues, eigenvectors, and canonical correlations appear. See Figure 5.4.
