PARETO Subcommand
Specification: var
PARETO creates one of two types of Pareto charts. A Pareto chart is used in quality control
to identify the few problems that create the majority of nonconformities. Only SUM, VALUE,
and COUNT can be used with the PARETO subcommand.
Before plotting, PARETO sorts the plotted values in descending order by category. The right
axis is always labeled by the cumulative percentage from 0 to 100. By default, a cumulative
line is displayed. You can eliminate the cumulative line or explicitly request it by specifying
one of the following keywords:
CUM Display the cumulative line. This is the default.
y-axis title: none
y-axis labels: number of valid cases
x-axis title: var label
x-axis labels: scaled values
The normal distribution line as well as the standard deviation, mean, and number of valid cases
are displayed.
NOCUM Do not display the cumulative line.
You can request a simple or a stacked Pareto chart by specifying one of the following
keywords and define it with appropriate function/variable specifications:
SIMPLE Simple Pareto chart. Each bar represents one type of nonconformity. A
simple Pareto chart can be defined by a single variable, a single VALUE function,
a single SUM function with a BY variable, or a SUM function with a variable
list as an argument with no BY variable (see Figure 52 and Figure 53).
STACKED Stacked Pareto chart. Each bar represents one or more types of nonconformity
within the category. A stacked Pareto chart can be defined by a single SUM
function with two BY variables, a single variable with a BY variable, a VALUE
function with a variable list as an argument, or a SUM function with a variable
list as an argument and a BY variable (see Figure 54 and Figure 55).
