The PARETO Procedure

Syntax: PARETO Procedure

The following statements are available in the PARETO procedure:

PROC PARETO <options> ;
BY variables ;
HBAR (variable-list )< / options> ;
VBAR (variable-list )< / options> ;
INSET keyword-list </ options> ;

You must specify the PROC PARETO statement and at least one HBAR or VBAR chart statement. A chart statement specifies the process variables that you want to analyze and produces a Pareto chart for each. You can specify any number of chart statements, and all other statements are optional.

The following statements request a vertical Pareto chart for the process variable Reason from the data set Failures. When the process variable-list contains only one variable, you do not need to enclose it in parentheses.

proc pareto data=Failures;
   vbar Reason;
run;

The following sections describe the PROC PARETO statement and then describe the other statements in alphabetical order.
