-
responses
-
identify one or more responses to be analyzed. The specification of response depends on the input data set specified in the PROC ANOM statement.
-
If response values (raw data) are read from a DATA= data set, response must be the name of the variable containing the values.For an example, see Creating ANOM Boxcharts from Response Values.
-
If summary data are read from a SUMMARY= data set, response must be the common prefix of the summary variables in the SUMMARY= data set. For an example, see Creating ANOM Boxcharts from Group Summary Data.
-
If summary data and decision limits are read from a TABLE= data set, response must be the value of the variable _VAR_
in the TABLE= data set. For an example, see Saving Decision Limits.
A response is required. If you specify more than one response, enclose the list in parentheses. For example, the following statements
request distinct ANOM charts for the means of Weight
, Length
, and Width
:
proc anom data=Measures;
xchart (Weight Length Width)*Day;
run;
-
group-variable
-
is the variable that identifies groups in the data. The group-variable is required. In the preceding BOXCHART statement, Day
is the group variable.
-
block-variables
-
are optional variables that group the data into blocks of consecutive groups. The blocks are labeled in a legend, and each
block-variable provides one level of labels in the legend.
-
symbol-variable
-
is an optional variable whose levels (unique values) determine the symbol marker used to plot the means. Distinct symbol
markers are displayed for points corresponding to the various levels of the symbol-variable. You can specify the symbol markers with SYMBOLn statements.
-
options
-
enhance the appearance of the chart, request additional analyses, save results in data sets, and so on. The section Summary of Options lists all options by function.
