Beneath the graph are the control buttons: Split, Prune, and Go. The Go button only appears if there is a validation set. Also shown is the name of the Treatment column and its two levels, called Treatment1 and Treatment2. If more than two levels are specified for the Treatment column, all but the first level are treated as a single level and combined into Treatment2.

The decision tree shows the splits used to model uplift. See Nodes for First Split for an example using the Hair Care Product.jmp sample data table. Each node contains the following information:

The t ratio for the test for a difference in response across the levels of Treatment for subjects in this node. If the response is categorical, it is treated as continuous (values 0 and 1) for this test.

The maximum logworth over all possible splits for the given term. The logworth corresponding to a split is -log10 of the adjusted p-value.

When the response is continuous, this is the coefficient of the interaction term in the linear regression model used in computing the F ratio. When the response is categorical, this is an estimate of the interaction constructed from Firth-adjusted log-odds ratios.

See Uplift Graph for an example of an Uplift Graph for the Hair Care Product.jmp sample data table after three splits and an additional specific split by Gender for the Hair Color (Black, Red Brown) group. Note that, for two groups of subjects (non-blond males in the Age ≥ 42 group, and blond-haired subjects in this group), the promotion has a negative effect.
