The Soviet answer on 4 May admonished Tito and the Communist Party of Yugoslavia (CPY) for failing to admit and correct its mistakes, and went on to accuse them of being too proud of their successes against the Germans, maintaining that the Red Army had saved them from destruction. Tito's response on 17 May suggested that the matter be settled at the meeting of the Cominform to be held that June. However, Tito did not attend the second meeting of the Cominform, fearing that Yugoslavia was to be openly attacked. In 1949 the crisis nearly escalated into an armed conflict, as Hungarian and Soviet forces were massing on the northern Yugoslav frontier. On 28 June, the other member countries expelled Yugoslavia, citing "nationalist elements" that had "managed in the course of the past five or six months to reach a dominant position in the leadership" of the CPY. The assumption in Moscow was that once it was known that he had lost Soviet approval, Tito would collapse; 'I will shake my little finger and there will be no more Tito,' Stalin remarked. The expulsion effectively banished Yugoslavia from the international association of socialist states, while other socialist states of Eastern Europe subsequently underwent purges of alleged "Titoists". Stalin took the matter personally and arranged several assassination attempts on Tito, none of which succeeded. In a correspondence between the two leaders, Tito openly wrote:
What was the name of those purged in other socialist states in Eastern Europe?
Titoists

Years later, Kaunitz kept trying to establish France's alliance with Austria. He tried as hard as he could for Austria to not get entangled in Hanover's political affairs, and was even willing to trade Austrian Netherlands for France's aid in recapturing Silesia. Frustrated by this decision and by the Dutch Republic's insistence on neutrality, Britain soon turned to Russia. On September 30, 1755, Britain pledged financial aid to Russia in order to station 50,000 troops on the Livonian-Lithunian border, so they could defend Britain's interests in Hanover immediately. Besthuzev, assuming the preparation was directed against Prussia, was more than happy to obey the request of the British. Unbeknownst to the other powers, King George II also made overtures to the Prussian king; Frederick, who began fearing the Austro-Russian intentions, and was excited to welcome a rapprochement with Britain. On January 16, 1756, the Convention of Westminster was signed wherein Britain and Prussia promised to aid one another in order to achieve lasting peace and stability in Europe.
What was Kaunitz of Austria willing to trade for French help in capturing Silesia?

Von Neumann made fundamental contributions to mathematical statistics. In 1941, he derived the exact distribution of the ratio of the mean square of successive differences to the sample variance for independent and identically normally distributed variables. This ratio was applied to the residuals from regression models and is commonly known as the Durbin–Watson statistic for testing the null hypothesis that the errors are serially independent against the alternative that they follow a stationary first order autoregression.
