The HPSPLIT Procedure
Syntax: HPSPLIT Procedure
The following statements and options are available in the HPSPLIT procedure:
-
PROC HPSPLIT <options>;
-
CLASS variable... </options>;
-
CODE FILE=filename;
-
GROW criterion </ options>;
-
ID variables;
-
MODEL response <(response-options)> = variable <variable...>;
-
OUTPUT output-options;
-
PARTITION <partition-options>;
-
PERFORMANCE performance-options;
-
PRUNE prune-method <(prune-options)>;
-
RULES FILE=filename;
The PROC HPSPLIT statement and the MODEL statement are required. If any variables are character or to be treated as categorical, at least one CLASS statement is required. Variables that appear after the equal sign (=) in the MODEL statement are explanatory variables that model the response variable. By default, all variables that appear in the MODEL statement are treated as continuous variables. CLASS statements cause 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 ignored and a warning to be issued.
The following sections describe the PROC HPSPLIT statement and then describe the other statements in alphabetical order.
