2020 Mock Exam B - Morning Session 第18题 请帮忙解答一下。 18 The change in which of the following items most likely indicates that CCCL might be recognizing revenue early? A Unearned revenue B Deferred tax assets C Days sales in receivables
已回答2020 Mock Exam B - Morning Session 第10题: 10 Using Exhibit 3 and Quinn’s reminder, the most appropriate measure of the accuracy of the model is: A 0.79. B 0.86. C 0.92. 文字描述: After running his model on the test set, Quinn produces a confusion matrix for evaluating the performance of the model (Exhibit 3). He reminds Wu that since the number of defaults in the dataset is likely much smaller than the number of non-defaults, this needs to be considered in evaluating model performance. ——通过这段文字,怎么能判断出题人要我用FIscore算, 而不是用Accurancy算??
已回答2020 Mock Exam B - Morning Session 第7题: Wu’s recollection about the preparation of the textual data is most accurate with respect to: A numbers. B stop words. C lowercasing. 题目描述: Wu tells Quinn that she has heard a little about text mining for clues about an individual’s behavior and recalls that text preparation must be carried out by removing such items as HTML tags, punctuation, numbers, and stop words and eliminating the distinction between uppercase and lowercase words by lowercasing them all. 这道题不是问正确的做法吗, 为什么选A呢? A numbers. ——不是应该在去掉后增加注释才正确吗? B stop words、C lowercasing——这两步应该是“数据处理”过程里的动作,不是“数据准备”里的动作,是这个意思吧?
已回答百题178页第二题,对应数据在正文第二段,红字部分是公式,我想问一下156000是clean price还是dirty price,如果是clean的话答案里没有加回AI0,如果是dirty的话麻烦明示一下哪里可以判断。然后想问一下AIT为啥是1166.76,我感觉6时点发生了coupon3500,到8时点应该3500*(2/12)只有答案的1/2,请问一下这里我的理解有什么问题,谢谢老师
精品问答
- 这题为什么是选C?
- 请老师讲解一下这个题目
- 老师,第二题可以在解释一下原理吗?
- 老师,第三题答案的意思是:1.因为宽松的货币政策,导致加元利率下跌,导致加元贬值?2.但是,如果利率下跌,也就是分母上的百分比下降,不是会导致价格上升吗?。3.从而短期看是depreciation,但是长期来看,会回归到均值,所以是appreciation?
- CDS的long和short是不是反过来的?就是long CDS代表看涨目标公司credit,所以是卖出一份CDS合约?
- 很迷惑到底是long call+ short stock还是long stock+short call构建无风险资产
- 为啥accrued interest over contract life是0?
- 这道题可不可以用算出来的fpa除以0.9算出的价格和125比较,得出的差额是套利的利润?
