Naive Bayes Platform Options
The Naive Bayes red triangle menu contains the following options:
ROC Curve
Shows or hides the Receiver Operating Characteristic (ROC) curve for the model. The ROC curve is a plot of sensitivity versus (1 - specificity) for each level of the response variable. The ROC plot is shown by default. If you used validation, a plot is shown for each of the training, validation, and test sets. See ROC Curves.
Precision Recall Curve
Shows or hides the Precision-Recall Curve plot that contains a curve for each level of the response variable. A precision-recall curve plots the precision values against the recall values at a variety of thresholds. If you used validation, a plot is shown for each of the training, validation, and test sets. See “Precision-Recall Curve”.
Lift Curve
Shows or hides the lift curve for the model. If you used validation, a lift curve is shown for each of the training, validation, and test sets.
A lift curve shows how effectively response levels are classified as their fitted probabilities decrease. The fitted probabilities are plotted along the horizontal axis in descending order. The vertical coordinate for a fitted probability is the proportion of correct classifications for that probability or higher, divided by the overall correct classification rate. Use the lift curve to see whether you can correctly classify a large proportion of observations if you select only those with a fitted probability that exceeds a threshold value.
If the response has two levels, the Lift curve plot displays a lift curve for the first level of the response only. If the response has more than two levels, the Lift curve plot displays a sub-outline of the curves for each response level. See “Lift Curve” for more information about lift curves.
Save Predicteds
Saves a new column to the data table. The column contains the predicted classifications. The column is called Naive Predicted <Y, Response>.
Save Prediction Formula
Saves a new column to the data table. The column contains the prediction formula for the classifications. The column is called Naive Predicted Formula <Y, Response>.
Save Probability Formula
Saves new columns to the data table. The columns contain the formulas that are used to classify each observation. Three groups of columns are saved:
Naive Score <Class>, Sum
For each column that represents a class, this column gives a score formula that measures strength of membership in the given class. In the Naive Score Sum column., these scores are summed across classes. See Statistical Details for Saved Probability Formulas.
Naive Prob <Class>
For each class, this column gives a formula for the conditional probability that an observation is in that class. See Statistical Details for Saved Probability Formulas.
Naive Predicted Formula <Y, Response>
Gives the formula for the predicted class.
Publish Probability Formula
Creates probability formulas and saves them as formula column scripts in the Formula Depot platform. If a Formula Depot report is not open, this option opens the Formula Depot window. See “Formula Depot”.
Profiler
Shows or hides the prediction profiler, which is used to graphically explore the prediction equation by slicing it one factor at a time. The prediction profiler contains features for optimization. Changes in the factor values are reflected in the estimated classification probabilities. See “Profiler” in Profilers.
See “Local Data Filters in JMP Reports”, “Redo Menus in JMP Reports”, “Group Platform”, and “Save Script Menus in JMP Reports” in Using JMP for more information about the following options:
Local Data Filter
Shows or hides the local data filter that enables you to filter the data used in a specific report.
Redo
Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.
Platform Preferences
Contains options that enable you to view the current platform preferences or update the platform preferences to match the settings in the current JMP report.
Save Script
Contains options that enable you to save a script that reproduces the report to several destinations.
Save By-Group Script
Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
Note: Additional options for this platform are available through scripting. Open the Scripting Index under the Help menu. In the Scripting Index, you can also find examples for scripting the options that are described in this section.
