解释：
Exhibit2验证的不是whether bond market return and stock market return explain the return of a portfolio…不应该是定性的Y？虽然没有这个选项
NO.PZ201709270100000208 问题如下 8. ShoulHonoré have estimatethe mols in Exhibit 1 anExhibit 2 using probit or logit mols insteof trationregression analysis? Both shoulestimatewith probit or logit mols. Neither shoulestimatewith probit or logit mols. Only the analysis in Exhibit 1 shoulne with probit or logit mols. B is correct. Probit anlogit mols are usefor mols with qualitative pennt variables, sumols in whithe pennt variable chave one of two screet outcomes (i.e., 0 or 1). The analysis in the two exhibits are explaining security returns, whiare continuous (not 0 or 1) variables. Exhibit 2.....establish whether bonmarket returns (proxiereturns of long-term US Treasuries) anstomarket returns(proxiereturns of the S P 500 Inx) explain the returns of a portfolio of utility stocks being recommento clients.这句话的意思不是说，是否bonmarket returns和stomarket returns可以什么什么吗？答案不就是要么能，要么不能吗？这个不是逻辑函数吗？
NO.PZ201709270100000208 请问，因为两个模型都用了WHETHER这个变量作为PENNT VARIABLE，那为什么不能属于Probit anlogit，答案也可以是O 或者1呀， 1 就是YES, O 就是NO。谢谢
老师好 一般什么情况下要用probit anlogit mols？谢谢
