关于FRM quantitative analysis的两个问题
1. Error term could possibly be explained by adding additional independent variables.这句话中的adding additional independent variables是什么意思？为什么error term可以被这个解释？
2. A linear regression function assumes that the equation must be linear in the coefficients but not necessarily the variables. 这句话是什么意思？
谢谢帮助~~~ |
