同學(xué)你好,Generate additional data using Monte Carlo simulation and merge it with the bank’s internal historical data.使用蒙特卡洛模擬來(lái)生成數(shù)據(jù),這是錯(cuò)誤的,數(shù)據(jù)不夠,就從其他渠道收集就可以了,蒙特卡洛這個(gè)技術(shù)不是用來(lái)解決數(shù)據(jù)不夠的問(wèn)題的
B.Estimate the parameters of a Poisson distribution to model the loss severity of operational losses.loss severity 用對(duì)數(shù)正態(tài)分布建模,不是泊松分布建模,B錯(cuò)誤
C.Estimate relevant probabilities using loss information that is published by credit rating agencies.評(píng)級(jí)機(jī)構(gòu)的數(shù)據(jù)為信用風(fēng)險(xiǎn)服務(wù)的,這里我們是估計(jì)操作風(fēng)險(xiǎn),所以還是不合適的,C錯(cuò)誤
D.Merge external data from other banks with the bank’s internal data after making appropriate scale adjustments.這個(gè)做法可以的,從其他金融機(jī)構(gòu)那里獲取數(shù)據(jù),但是數(shù)據(jù)會(huì)經(jīng)過(guò)規(guī)模的調(diào)整,沒(méi)有問(wèn)題,答案選D
