    Creating a difference measure on a time series

    Jes Lee

      Hello,

       

      I'm trying to create a difference measure on a time series where I would like to most current period to represent the change over the previous period.   For instance, if the original time series is as follows:

       

      2015    10

      2014      8

      2013     5

      2012    4




      I would like to create a new series:


      2015    2

      2014    3

      2013    1



      How would I go about doing this? 



      Thank you,
