Overview
The clario® node Rank allows you to rank records in a data stream by looking at the values of an attribute and assigning them a “score” based on their relative value to all values within the attribute.
Usage
Input Stream
The node connector can be connected to a variety of nodes, (ie. Read, Outliers, Missing, etc.), but requires a valid stream of data.
Configuration
The Rank node has only one configuration face.
Configuration Face
The configuration face contains four different tabs requiring your interaction. Selecting a key attribute to rank by, selecting a Tie Break Method (mean, low, high), selecting a # of segments (number of rank groups) and name a New Rank Attribute. The Attribute to Rank drop down displays all of the attributes for the input data stream connected to the input link node connector. The Tie Break Method drop down displays options for ranking scores that are tied. The segments box defines the number of groups into which observations should be ranked. For example, if 5 segments are selected, the observations will be ranked into 5 relatively equal groups with a rank value of 1-5. The rank of 5 separates the group with the highest 20% of values for the ranked attribute. The maximum value for # of segments is 99. And finally, the node enables you to edit the name of the new attribute by typing in the "New Rank Attribute" text box (the default name is "<Attribute Name>_Rank").
IMPORTANT: Only one attribute can be selected to define the rank.
Results
There is no results face for the Rank node. It is assumed the Rank node will be connected to another node to analyze the data set by Rank or written out into a file.
Output Stream
The newly ‘Ranked’ dataset is ready for immediate use in various nodes located throughout clario. The data can be exported using the Write File node and can then be used again by reading in the file with the Read File node.
