Dependent Variable: LAND? Land为因变量
Method: GLS (Cross Section Weights) 估计方法为广义最 ...
请问EVIEWS检验中Total panel (unbalanced) observations是什么意思,怎么计算的
我得出的结果Total panel (unbalanced) observations太小了,感觉不太符合情况,你能帮我看看吗,我的截面数据有66个,时期是10年,总共观察值应该是660个,但是因为有一个指标缺失了较多的数据,可是也不会是只有72个啊,结果如下
Dependent Variable: LOG(Y)
Method: Panel Least Squares
