问题如下:
8. Should Honoré have estimated the models in Exhibit 1 and Exhibit 2 using probit or logit models instead of traditional regression analysis?
选项:
A. Both
should be estimated with probit or logit models.
B. Neither
should be estimated with probit or logit models.
C. Only
the analysis in Exhibit 1 should be done with probit or logit models.
解释:
B is correct. Probit and logit models are used for models with qualitative dependent variables, such as models in which the dependent variable can have one of two discreet outcomes (i.e., 0 or 1). The analysis in the two exhibits are explaining security returns, which are continuous (not 0 or 1) variables.
Exhibits 1的dummy variable 不是选0和1吗?为什么不能选,谢谢
