  2. Quantitative

NO.PZ2018101001000023

问题如下：

Xiao Ming does the multiple regression analysis to find that how GDP 、 financial deficit(FD) and repayment of principal(REPAY) influence the total volume of national debt(DEBT) in China and gets the following model: DEBT=4.31+0.35GDP+1.00FD+0.88REPAY. Which of the following statements is most likely correct?

选项：

A.

Repayment of principal and the total volume of national debt are negatively related.

B.

When financial deficit decrease, the total volume of national debt increases.

C.

The increase of the GDP will increase the total volume of national debt.

解释：

C is correct.

考点: Interpret Regression Coefficient, Assumptions and F-test.

解析: 通过每个变量前面的斜率的正负号我们可以知道GDP、financial deficit and repayment of principal这三个变量对total volume of national debt都有正向的影响。而选项A和B的描述都说反了，所以错误，应该选择C。

每当FD增加1个单位，Debt增加0.35个单位，所以，B正确？

嗨，努力学习的PZer你好：


B选项说的是FD减少，debt会增加。由于FD的系数为负，所以这个描述错误。
