    参考本章例5-6。回归结果表明,1958~1969年的小时工资变化率和失业率与传统的菲利普斯曲线吻合。现考虑1965-2007年的数据(参见网上教材表5-19)。a.做小时工资变化率([tex=0.643x1.0]O+viFNA0oHTwnBtQyi80Zw==[/tex])对失业率([tex=0.857x1.0]N7iCrOsS+NNEUUlnsYCi1g==[/tex])的散点图。图形是否呈现线性模式?b. 做[tex=0.643x1.0]jDVSpgNhHe+VJmgvx3gg1Q==[/tex] 和[tex=1.071x2.357]EASA4KVg44+JZTsFRyw1FQ==[/tex]的散点图。与( a) 相比, 图形是否呈现出更明显的线性模式?c. 利用新数据拟合式 (5-29)。模型的拟合效果如何? 建立一个形如式 (5-30)的 LIV 模型。哪一个模型更好? 为什么?
