Statistics (Explore)

Click the Statistics tab to specify the statistics to calculate. You can also change statistics in the Statistics section of Explore node Properties pane.

The statistics tab contains a list of statistics available. For each statistic, there is a brief definition and an indication of the cost to calculate that statistic.

If you change any of the default selections, click Restore Defaults to change all selections to the default selections.

By default, Oracle Data Miner calculates these statistics:

The default statistics have a low or medium cost to calculate.

Skewness and kurtosis have a high cost to calculate. They are not selected by default. You can select them if necessary.

Calculating mode using a sample is a low cost operation. Calculating the mode using all available data is a very high cost operation. To calculate mode using sample data or all available data, click Mode (Sampled) in the Edit Explore Data Node dialog box.
