I use calculated index in your paper. I must show the method of calculation this index from 1980 to 2014.

Please explain for me, how can I calculate this index for Iran for one year?

How did you use from your sources that you have introduced?

Can I calculate this index whit these data in your paper?

I need your help. Please answer me with regards. ]]>

The information on how to do this is contained in the paper. But no, you need to have data for all (available) countries to extend this past 2010, because each indicator is first normalised (0-100 scale), then standardised with respect to the base year of 1980. Using the raw numbers for a single country therefore won’t work.
