The TREESPLIT Procedure
Syntax: TREESPLIT Procedure
The following statements and options are available in the TREESPLIT procedure:
PROC TREESPLIT <options>;
AUTOTUNE <options>;
CLASS variables;
CODE <options>;
FREQ variable;
GROW criterion <options>;
MODEL response = variable…;
OUTPUT OUT=CAS-libref.data-table output-options;
PARTITION <partition-options>;
PRUNE prune-method <(prune-options)>;
VIICODE <options>;
WEIGHT variable;
The PROC TREESPLIT statement and the MODEL statement are required. If any variables are character or are to be treated as categorical, at least one CLASS statement is required. Variables that appear after the equal sign (=) in the MODEL statement are predictor variables that model the response variable. By default, all variables that appear in the MODEL statement are treated as continuous variables. A CLASS statement causes a variable to be treated as categorical. Specifying a variable in a CLASS statement but not in a MODEL statement causes the variable to be implicitly added to the MODEL statement.
The following sections describe the PROC TREESPLIT statement and then describe the other statements in alphabetical order.
