Overview

The clario^® node Indicators is used to create indicator or dummy attributes from string attributes by taking each unique value of a string attribute and turning it into an indicator or dummy attribute. The node performs a ‘One for All’ method of creating indicators. This will create one indicator attribute for each unique value of the selected string attribute.

Usage

Input Stream

Indicators can be connected to the Read File node or other valid data streams.

Configuration

The indicators node has only one configuration face.

Configuration Face

The configuration face contains an Available Attributes and a Selected Attributes list box. The Available Attributes list box displays all of the string attributes for the input data stream connected to the input link node connector. The first and only step with this face is to select, drag and drop the desired attributes from the Available Attributes list box to the Selected Attributes list box.

NOTES: To efficiently find attribute names, begin typing an attribute name in the text box directly above Available Attributes. You will then be directed to only the attribute(s) beginning with the letter(s) you type. To select multiple attributes at once, either use [Ctrl]+click to select multiple, one at a time, [Shift]+down arrow to select multiple in order of appearance, or use [Shift]+click to select the beginning and the ending attribute which will select all attributes. To de-select an attribute click on the attribute in the Selected Attributes box and drag and drop into the Available Attributes box. Attributes in the Selected Attributes list can be re-ordered by clicking and holding on an attribute and dragging it to the desired position within the Selected Attributes box.

If the results are to be saved to a file, check the Save to File checkbox, click on the file browse button [...] and enter/select the file name and click [OK]. Otherwise make sure it is left unchecked.

Field Definitions

• Valid Inputs – You must link to a valid data set

• At least 1 attribute must be placed in the "Selected Attributes" list.

Results

There is one results face for the Create Indicators node which contains the following:
View Summary – Contains indicator processing summary. View summary will show one row of data for each attribute selected with three different result columns (number of Observed Values, number of Missing Values, and Number of Indicators Created).

View Pseudo Code – Contains rules for how the Indicators will be created.

Output Stream

Create Indicators is a terminal node. Therefore, in order for the newly created indicators to be utilized in other clario processes, the resulting file must be written out and re-read in. The data export does not require a Write File node, as the ‘Save to File’ option will write out a new file with the original data and new indicators. However, the Read File node is needed to bring the dataset back into processing.
