同學(xué)你好，
B選項：Begin monitoring the performance of each model only after the backtest of the model has been successfully completed.【回測之前就要監(jiān)控，監(jiān)控是全流程的】
C選項：Ensure that third-party vendor models used by the bank are implemented under the assumptions that were initially provided by the vendor.【現(xiàn)實世界是多變的，模型設(shè)計之初的假設(shè)條件很有可能不再相同，這個時候模型依然可以使用，但是需要調(diào)整。最典型的案例應(yīng)該就是次貸危機期間的CDO模型使用了早期的相關(guān)系數(shù)估計，沒有在危機期間調(diào)整相關(guān)系數(shù)參數(shù)導(dǎo)致模型結(jié)果出錯】
