由于SDM没有考虑残差空间自相关,想要解决问题只能采用更高级的空间计量模型。可以看更新的关于SARAR(Spatial Autoregressive Model with Autoregressive Errors)或者一些其他牛逼模型的论文。 LR检验 刚才说LM检验是判断模型是否应该“进化”的检验,LR和wald检验是用来判断是否能够“退化”简化的检验。 LR检验(Likelihood Rati...

这些常见的空间计量经济学模型都基于一个共同的母版,称为广义嵌套空间模型(Generalized Nested Spatial Model, GNSM)。 空间效应的判断 在研究过程中,如果通过莫兰指数等方法发现研究对象具有空间效应,应选择空间计量模型而非传统的普通最小二乘回归模型(OLS)。
