同學(xué)你好,I. Stress tests tend to analyze a shorter period of time compared to EC methods.壓力測試的關(guān)注期可達(dá)到9個(gè)季度,但EC關(guān)注期最多是一年,所以前者的時(shí)間更久,這句話錯(cuò)誤
II. Stress tests tend to compute losses from the perspective of the market as opposed to EC methods that compute losses from an accounting perspective.,壓力測試的損失最終會(huì)體現(xiàn)在財(cái)務(wù)報(bào)表上,記錄在財(cái)務(wù)報(bào)表上的數(shù)據(jù)是基于會(huì)計(jì)的視角的,而EC的數(shù)據(jù)來源于市場數(shù)據(jù),根據(jù)市場損失數(shù)據(jù)計(jì)算出VAR,進(jìn)一步得出EC,所以它的數(shù)據(jù)視角是基于市場的,這句話說反了
III. Stress tests tend to use ordinal rank arrangements, while EC methods use cardinal probabilities.壓力測試關(guān)注的是排序,也就是情景的嚴(yán)重程度,比如溫和的情景,嚴(yán)重的情景,非常嚴(yán)重的情景,從前往后,越來越糟糕,這是排序即ordinal rank,而EC關(guān)注的是概率,比如95%的置信水平,99%的置信水平,根據(jù)不同的置信水平可以計(jì)算不同的EC,這里的95%,99%都是指的概率,所以這句話是對(duì)的
IV. Stress tests tend to focus on unconditional scenarios, which EC methods tend to focus on conditional scenarios.
壓力測試關(guān)注的情景都是有條件的,conditional scenarios,前提條件是比較糟糕,所以才叫壓力測試,而EC不關(guān)注情景,unconditional scenarios,只要能獲取到數(shù)據(jù),就能去計(jì)算EC,所以這句話說反了,錯(cuò)誤
