In the original publication of the article, the reference “Fortna (2004)” is cited incorrectly both in the text and in the reference list.

In section 2, entitled “Constructing a Durable Peace Index”, in the second paragraph, Fortuna (2004) should be changed to Fortna (2004). And in the reference list, Fortuna VP (2004) should be changed to Fortna VP (2004).
