Statistics

Finally, the transaction flows to a Bucket, which collects transactions and can also save the value of transaction attributes in a SAS data set.

Figure 1.7: A Bucket Control Panel

From the bucket control panel (Figure 1.7) you can set the size of the transaction collection buffer and name the transaction attribute to accumulate. You can also name a SAS data set into which to collect the transaction attribute values.

Figure 1.8: Statistics on a Transaction Attribute

If you collect data into a SAS data set and then press the Analyze button, univariate statistics will be calculated by the UNIVARIATE procedure (Figure 1.8) and a sample distribution function as shown in Figure 1.9 will be plotted.
