Random Trees node - advanced

Specify advanced options for how to build the decision tree.

Maximum percentage of missing values. Specify the maximum percentage of missing values allowed in any input. If the percentage exceeds this number, the input is excluded from model building.

Exclude fields with a single category majority over. Specify the maximum percentage of records that a single category can have within a field. If any category value represents a higher percentage of records than specified, the entire field is excluded from model building.

Maximum number of field categories. Specify the maximum number of categories that can be contained within a field. If the number of categories exceeds this number, the field is excluded from model building.

Minimum field variation. If the coefficient of variation of a continuous field is smaller than the value you specify here (in other words, the field is nearly constant), then field is excluded from model building.

Number of bins. Specify the number of equal frequency bins to be used for continuous inputs. The available options are: 2, 4, 5, 10, 20, 25 ,50, or 100.

Number of interesting rules to report. Specify the number of rules to report (minimum of 1, maximum of 1000, with a default of 50).
