Methods for data sets

Data sets can contain multiple data series, which can contain multiple items. You use data set methods to return a data set that is a subset of the original data set. Data set methods always return a data set, not a single value.

Methods for data sets appear in the Rule Wizard in the Expression tab > Data Mappings tab. The list of methods that appear is based on the selection of standard data dimensions and the creation of custom data dimensions in the definition of the data set. In addition to the data set methods listed in the following table, one method appears for each custom dimension that is created for the data set.

To use a method in a rule expression:

  1. Double-click the method.

    If the method has one or more parameters, the Invoke Function dialog box appears.

  2. Drag a study object from the References tab to the Values field to define a value for each parameter.
