IMSTAT Procedure (Analytics)

Example 2: Retrieving Box Values

Details

This PROC IMSTAT example demonstrates retrieving the statistics for a box plot. The BOXPLOT statement does not generate a plot, it generates values that can be used to create a plot.

Program

libname example sasiola host="grid001.example.com" port=10010 tag='hps';

data example.cars; 1
    set sashelp.cars;
run;

proc imstat data=example.cars; 2
    boxplot;
quit;

Program Description

The sashelp.cars data set is loaded to memory on the SAS LASR Analytic Server.
The in-memory table is referenced with the DATA= option and then the BOXPLOT statement is used.

Output

The arithmetic mean is reported because the center line of the box plot is sometimes drawn at the mean and not the median. In some displays the median is shown as a line and the box is augmented with a graphic symbol at the position of the mean. The low and high whiskers are values of actual observations in the data set. These values might be the minimum or maximum values in the data set if the value for that observation equals the value nearest 1.5 times the inter-quartile range from the edge of the box. The box in box plot is drawn from the first quartile to the third quartile.
