The Details tab allows you to view details for a cluster. You can discover what values of an attribute are in the selected cluster.
The viewer supports filtering so that only selected probabilities are displayed.
The following information is displayed:
Cluster: The ID of the cluster being viewed. change the cluster by selecting a different ID from the menu. You can select Leaves Only to view terminal clusters only.
Fetch Size: The number of columns selected. The default is 50; you can change the fetch size. If you change the fetch size, click Query.
Information about the attributes in the selected cluster are listed in a grid.
The grid lists the attributes in the cluster. For each attribute, the following information is displayed:
Attribute name
Histogram of the attribute values in the selected cluster
Confidence displayed as both a number and with a bar indicating a percent. If confidence is very small, no bar is displayed
Support, the number of cases
Mean, displayed for numeric attributes
Mode, displayed for categorical attributes
Variance
You can sort the attributes in the cluster by Confidence, Support, Mean, Mode, Variance Attribute name in either ascending or descending order. To sort, click the appropriate column heading in the grid; for example to sort by attribute name, click Attribute.
You can search the attribute list for a specific attribute name or for a specific value of mode.To search, use the search box next to
The drop down menu allows you search the grid by Attribute (the default) or by Mode. Type the search term in the box.
To clear a search, click
To view a larger version of the histogram, select an attribute; the histogram is displayed below the grid. Float the cursor over a bar in the histogram to see details of the histogram including the exact value.
