Uplift Report Options
With the exception of the options described below, all of the red triangle options for the Uplift report are described in the documentation for the Partition platform. For more information about these options, see Partition Models in Predictive and Specialized Modeling.
Minimum Size Split
This option presents a window where you enter a number or a fractional portion of the total sample size to define the minimum size split allowed. To specify a number, enter a value greater than or equal to 1. To specify a fraction of the sample size, enter a value less than 1. The default value for the Uplift platform is set to 25 or the floor of the number of rows divided by 2,000, whichever value is greater.
Column Uplift Contributions
This table and plot address a column’s contribution to the uplift tree structure. A column’s contribution is computed as the sum of the F Ratio values associated with its splits. Recall that these values measure the significance of the treatment-by-split interaction term in the regression model.
Uplift Graph
Consider the observations in the training set. Define uplift for an observation as the difference between the predicted probabilities or means across the levels of Treatment for the observation’s terminal node. These uplift values are sorted in descending order. On its vertical axis, the Uplift Graph shows the uplift values. On its horizontal axis, the graph shows the proportion of observations with each uplift value.
Save Columns
Save Difference
Saves the estimated difference in mean responses across levels of Treatment for the observation’s node. This is the estimated uplift.
Save Difference Formula
Saves the formula for the Difference, or uplift.
Publish Difference Formula
Creates the difference formula and saves it as a formula column script in the Formula Depot platform. If a Formula Depot report is not open, this option creates a Formula Depot report. See Formula Depot inPredictive and Specialized Modeling.
