Reliability between evaluators is the degree of agreement between evaluators or judges. If everyone agrees, the IRR is 1 (or 100%) and if everyone does not agree, the IRR is 0 (0%). There are several methods for calculating IRR, from the simplest (e.B percent) to the most complex (e.B Cohen`s Kappa). Which one you choose depends largely on the type of data you have and the number of evaluators in your model. Although Yugoslavia was not considered as important as Italy and Greece, Churchill had pushed in June 1944 for a coalition government in which the provisional government of democratic federal Yugoslavia, proclaimed in 1943 by Field Marshal Josip Broz Tito, would unite with the London-based Yugoslav government-in-exile under Royal Peter II. Churchill hoped that with the help of Stalin`s Tito, he could persuade King Peter II to succeed. He believed that maintaining the house of Karađorđević would ensure that Yugoslavia would remain at least partially under British influence after the war.  However, unlike Greece and Italy, where British ships had to pass on the Suez Canal route, this was not the case for Yugoslavia, which led Churchill to attach less importance to this nation.
