為啥用e的指數(shù)計算
為什么The variance of the error term is the same for all observations.對了？不應(yīng)該是方差穩(wěn)定嗎，怎么能值相同
老師歸類一下非參數(shù)檢驗適合的場景唄
A pooled estimator is used when testing a hypothesis concerning the:A.equality of the variances of two normally distributed populations.B.difference between the means of two approximately normally distributed populations with unknown but assumed equal variances.C.difference between the means of two at least approximately normally distributed populations with unknown and assumed unequal variances.這道題沒太明白啥意思
A population has a non-normal distribution with mean μ and variance σ2. The sampling distribution of the sample mean computed from samples of large size from that population will have:A.the same distribution as the population distribution.B.its mean approximately equal to the population mean.C.its variance approximately equal to the population variance.為啥A不對，大樣本不是可以看成正態(tài)嗎，為什么b對c不對

老師，long/short不是一個動作來的嗎，買入/賣出，call/put才是希望持有的頭寸是漲還是跌。那這里short，不是意思是賣出嗎，那既有可能是賣出call，也有可能賣出put。那當賣出call，由于underlying的價格可以無限上漲，所以損失可以無限。當賣出的是put，由于underlying價格最低為0，執(zhí)行價理應(yīng)是低于現(xiàn)價，所以獲利是有限的。 從這個角度理解是對的嗎？
對于無形資產(chǎn)，為什么CASH FLOW模式更合適？怎么算法？無形資產(chǎn)的現(xiàn)金流有哪些
