The main conclusions are : the ruin probability of the risk process is increasing according to the relativity of the classes ; and with the initial surplus increasing , the influence of the relativity to the ruin probability is increasing 主要結(jié)論為:隨著類(lèi)之間的相關(guān)度增加,則相應(yīng)的風(fēng)險(xiǎn)過(guò)程的破產(chǎn)概率也隨著增大,且隨著初始盈余的的增大,相關(guān)性對(duì)破產(chǎn)概率的影響也越來(lái)越顯著。
