Building a Model with Elementary Components

Bucket

The bucket is a component for collecting statistics on an attribute and saving its values in a SAS data set. You name an attribute for which you want to collect statistics in the Bucket control panel. The attribute "age" is the default collected. You can also specify the buffer size, which is the number of values of the attribute that is used in calculating statistics and displaying in the chart component. There is also a way to name a data set into which the attribute's values are saved and a way to start and stop data collection. In addition, the 'Reset' button empties the buffer and the 'Ok' button sets the buffer size and attribute names.

When you select the Collect Data check box, for each transaction the values of the monitored attribute are saved in a SAS data set. Chapter 8, "Saving and Restoring," discusses the details of this data set. You can analyze the data you collect by pressing the Analyze button which executes PROC UNIVARIATE and PROC GPLOT. Chapter 9, "Analyzing the Sample Path," discusses the details of the type of analysis.
