Brazil was the winner of 2002 FIFA World Cup Korea/Japan.
巴西隊曾獲2002年韓國/日本世界杯足球賽的冠軍。
UBS bankers have used a mathematical model to predict the champions of the South Africa 2010 World Cup – and say England and Spain have just 4pc chance of winning.
瑞士銀行的分析人士利用數學模型對今年南非世界杯鹿死誰手進行了預測-并且稱,英格蘭隊和西班牙隊僅有4%的奪冠幾率。
Brazil, who have claimed the trophy a record five times, are the likely winners this summer, with 22pc probability of victory, the Swiss investment bank said.
瑞士投資銀行表示,曾獲五次世界杯冠軍的巴西隊是本屆世界杯的奪冠熱門,有22%的奪冠幾率。
The UBS Wealth Management team found Spain, the European champions and bookmakers' favorite, to have just a 4pc shot at the title. Fabio Capello's England also has just a 4pc chance, it said.
瑞銀財富管理研究小組指出,歐洲杯冠軍、賭球者的最愛西班牙隊只有4%的奪冠幾率;而卡佩羅率領的英格蘭隊也區(qū)區(qū)只有4%的奪冠幾率。
"Football fans may feel that the European champions and firm fans favorite Spain is under-rated by the UBS model," the bank's global equity research team said in its World Cup 2010 research paper on Wednesday."And our local UK readers may feel the same about England’s chances. However, both teams have tended to be underachievers when it comes to the World Cup finals themselves. In the last three events, Spain and England were ranked amongst the strongest teams but did not make it beyond the quarter-final stage.
上周三,瑞銀的全球證券研究小組在一份針對2010年世界杯的調查報告中稱,“球迷們可能覺得西班牙隊被瑞銀的這個預測模型低估了。英國的球迷也會覺得英格蘭隊被低估了。然而,這兩支隊伍往往到了決賽階段就表現不佳。在頭三個賽季里,西班牙和英格蘭位列諸強,但卻紛紛止步于四分之一決賽?!?/div>
"Brazil has the highest probability [of winning]."
“巴西最有可能贏?!?/div>
UBS used its "econometric toolbox and quantitative models" to forecast the winner based on factors including historic results and the teams' current "Elo ratings" – which take account of not only recent wins, losses and defeats, but the conditions under which those events occurred. Beating a powerhouse like Brazil or Spain would improve a team’s Elo ranking much more than beating a smaller side like Malta or Andorra.
瑞銀根據各個球隊的歷史成績和當前的積分排名情況(積分不單單考慮到球隊近期的輸贏,還考慮到了比賽中的具體情況。比如,擊敗一支強隊(如巴西隊、西班牙隊)能夠獲得的積分要比擊敗一直弱隊(如馬耳他隊、安道爾隊)多很多。),利用“經濟計量工具箱和定量模型”來預測本屆世界杯的冠軍得主。
The bank also believes World Cup hosts South Africa, despite their uninspiring recent form, are all but guaranteed a place in the second round, rating their chances at 78pc.Brazil are the second most likely to progress with 74pc. The country least likely to progress, with a probability of just 29pc, is Paraguay, UBS said.
瑞銀還認為,本屆世界杯東道主南非隊雖然近來士氣不旺,也有78%的幾率能進入淘汰賽。巴西隊的晉級率位居第二,為74%。晉級率最低的當屬巴拉圭隊,僅為29%。
England was rated 63pc likely to escape the group stage and 21pc guaranteed to reach the semi-finals.
英格蘭隊的出線率為63%,進入半決賽的幾率為21%。
The UBS model was applauded in 2006 when it selected the winner, Italy. The bankers also correctly predicted 13 of the final 16, six of the final eight, and two of the semi-finalists.
在2006年世界杯的角逐中,瑞銀利用預測模型預測意大利隊最有可能奪冠,并最終言中,該預測模型也因此受到了人們的好評。此外,瑞銀還曾成功預測了16強中的13支球隊以及八強中的6支球隊。
However, when using the model for the 2008 European Championship, the forecast winner did not make it to the second round. "The moral of the story is that one needs to be humble about the predictive power of one’s model," the Wealth Management team said.
不過,該模型在2008年歐錦賽中預測的奪冠熱門球隊卻未能進入第二輪。瑞銀財富管理團隊對此表示,“對該模型的預測能力我們還是保守一點為妙?!?/div>
