Figure 8.6 Naive Bayes Launch Window
The Naive Bayes launch window provides the following options:
Y, Response
The categorical response column whose values are the classes of interest.
X, Factor
Categorical or continuous predictor columns.
Weight
A column whose numeric values assign a weight to each row in the analysis.
Freq
A column whose numeric values assign a frequency to each row in the analysis.
Validation
A numeric column that contains at most three distinct values. See Validation in Partition Models.
Note: If neither a Validation column or a Validation Portion is specified in the launch window and if there are excluded rows, these rows are treated as a Validation set.
By
A column or columns whose levels define separate analyses. For each level of the specified column, the corresponding rows are analyzed using the other variables that you have specified. The results are presented in separate reports. If more than one By variable is assigned, a separate analysis is produced for each possible combination of the levels of the By variables.
Validation Portion
The portion of the data to be used as the Validation set. See Validation in Partition Models.
