金程問(wèn)答精 Which of the following statements is the best direct reflection of the location-scale invariance property of the normal distribution?老師,這個(gè)題目挺簡(jiǎn)單,答案是很容易理解。但是做的時(shí)候,他問(wèn)的問(wèn)題我沒(méi)太理解。什么叫the location-scale invariance property
精 怎么判斷是價(jià)格高低估還是收益率高低估呢
精 這個(gè)題沒(méi)有視頻解析,不明白,能對(duì)每個(gè)選項(xiàng)具體解釋一下嗎
精 老師這個(gè)第二問(wèn)是不是實(shí)在是t test可以部分自變量顯著解釋因變量,雖然過(guò)程很麻煩
精 可以解釋一下這道題嗎
精 還是不太懂這個(gè)記息天數(shù)這三個(gè)是怎么算的。為啥2.28到3.1號(hào)公司債是3天,Money market是1天呢?咋算的
精 為什么深度實(shí)值歐式看跌期權(quán),theta>0,突然忘記了
精 老師,這一頁(yè)說(shuō)的是啥意思,我怎么感覺(jué)跟基初段講的不太一樣,這個(gè)是為了說(shuō)明下一頁(yè)的兩個(gè)圖?還是說(shuō)僅僅是要記住這兩句話?有點(diǎn)不明白這一頁(yè)在干嘛
精 老師可以解釋一下14題嗎?
精 可以解釋一下由負(fù)久期怎么推出下面的選項(xiàng)的?
精 老師,題目中說(shuō)哪個(gè)不是違背假設(shè),自相關(guān)是違背了哪一條假設(shè)?
精 Suppose that a bank has a portfolio with 10,000 loans, and each loan is EUR 1 million and has a 0.5% PD in a year. Also assume that the recovery rate is 30% and correlation between losses is 0.2. Calculate the standard deviation of the loss from the loan portfolio and the standard deviation of the loss as a percentage of its size.
精 第8題在哪里PPT講過(guò)
精 老師1和4不理解
精 CML為什么是SML的特例呢?
