Standard Deviation

      Standard Deviation

      I'd like to make a standard deviation with Rules.

      -Seems to be pretty complicated to go from the node, and calculate the difference between average and value from base elements...
      - It also seems to be not possible to go from the Base Element, as you don't know which Nodes are used for consolidation...

      Any Idea how to do it, if its possible ?
      I know this is old. But for anyone else who stumbles upon this topic:

      I give a try to do this during the load of the data. There is the possibility to integrate scipts powered by the programming language R which makes calculation of data quite handy.

      A standard deviation is rediculously easy with R.
