非常感谢楼主的总结整理,最近写论文用到面板数据模型,帮助很大。已仔细阅读过面板数据章节,有两个小疑问,望多多指导:(1)Breusch-Pagan test和Hausman test中P 是0.00reject H0,还是小于0.05就好?(2)文中指出,“Overall var=between var + within var(解释:for lstocka, between variance dominates,more than 80% of the overall variation is due to differences across firms )”,对应表格中数据为lstocka Std. Dev. 13.48467,between12.65423,within5.442742,数字之间的勾稽关系好像不太对?80%具体怎么计算的,希望可以展示一下。非常感谢!
