Select the graphs that you want to display for the analysis.
The available plot depends on the criterion that you choose to select the optimal number of trees. The plot shows the relationship between the criterion and the number of trees.

 Variable importance chart

The variable importance
chart shows the relative importance of the predictors. You can choose whether to display all or some of the important variables. Variables are important when they are used as primary splitters.
 Display all important variables: By default, this chart displays all important variables.
 Display a percentage of important
variables: Specify the percentage of important variables to display. Enter a value between 0 and 100.
 Display all predictor variables: Display all predictors whether or not they are important variables.
 Receiver operating
characteristic (ROC) curve

The receiver operating characteristic (ROC) curve shows the ability of a model to distinguish between classes. The ROC curve plots the true positive rate (TPR) against the false positive rate (FPR).
 Gain
chart

The cumulative gain chart illustrates the effectiveness of the model in a portion of the population. The gain chart plots the true positive rate in percent versus % population.
 Lift
chart

The lift chart illustrates the effectiveness of the predictive model. The chart plots cumulative lift versus % population and displays the difference between results obtained with and without the predictive model. You can specify Cumulative or Not
cumulative for the lift chart.
 Boxplot
of event probabilities

For a binary response, the boxplot of event probabilities displays the distribution of event probabilities for both the test and training data.
 One
predictor partial dependence plot for top K important variables, K
=

The one predictor partial dependence plots display the fitted half log odds values for the top 4 important variables, by default. You can increase or decrease the number of important variables to plot. After you have results, click Select More Predictors to Plot underneath the onepredictor plots to show plots for more predictors.
 Two
predictor partial dependence plot for top K important variables, K
=

The two predictor partial dependence plots display the fitted half log odds values for the top 2 important variables, by default. You can increase or decrease the number of important variables to plot. After you have results, click Select More Predictors to Plot underneath the twopredictor plots to show plots for more pairs of predictors.
 For plots with categorical predictors, Minitab plots a scatterplot of the fitted values. For continuous predictors, you can specify Surface, Contour plots, or both.
