Response information table for CART^® Classification

The Response Information table shows the breakdown of response data into levels, before any splits. The data in this table match the data in the root node of the tree.

Variable

Name of the response variable.

Class

Levels of the response variable.

Count

Number of observations at each level of the response variable.

%

Percentage of observations at each level of the response variable.

If you select a tree with a test set instead of with cross-validation, Minitab displays results for the Training and Test sets for comparisons. Use the Test results to evaluate the performance of the classification tree. The training data set is used to grow and prune the tree, while the test set is used to select the tree.

Training Count

Number of observations at each level of the response variable for the training data set.

Training %

Percentage of observations at each level of the response variable for the training data set.

Test Count

Number of observations at each level of the response variable for the test data set.

Test %

Percentage of observations at each level of the response variable for the test data set.
