Objects are the lists of specific items on which the calculation can be performed. Although the primary place for objects is the "Rows" pane, they can be placed also in "Columns" pane (as split only) or used as a filter. In order to use an object drag it and drop in a proper pane. Alternatively, left click on menu or right click on object name will open object context menu, allowing you do add the object to any of the panes.

 

 

Objects can be nested one in the other or split by a regular question nested in it. Read more in: Nesting.

 

It is possible for some objects to be used in more than one variant (if they are defined). The variants may differ e.g. by the level of granularity.
