问题如下图:
选项:
A.
B.
C.
解释:
不选A的原因是因为题干给了DW值,但没有给DW critical value,无法判断A选项,所以才不选,对吗?
NO.PZ201709270100000505 问题如下 5. Baseon the regression output in Exhibit 2, whshoulleBusse to conclu ththe Regression 3 equation is not correctly specifie A.The rbin–Watson statisti B.The t-statistic for the slope coefficient C.The t-statistifor the autocorrelations of the resi C is correct. The regression output in Exhibit 2 suggests there is sericorrelation in the resierrors. The fourth autocorrelation of the resiha value of 0.6994 ana t-statistic of 4.3111, whiis greater ththe t-statistic criticvalue of 2.02. Therefore, the null hypothesis ththe fourth autocorrelation is equto zero crejecte This incates strong ansignificant seasonautocorrelation, whimeans the Regression 3 equation is misspecifie test,这个得出的数字值小于CriticValue啊,那为什么A不对啊

b哪里错了?b哪里错了?
