Stata的xtnbreg是Stata软件中用于估计非线性固定效应负二项回归模型的命令。它主要用于处理二项分布的计数数据,同时考虑了固定效应和非线性关系。xtnbreg命令在Stata中是独有的,没有对应的R函数。 非线性固定效应负二项回归模型适用于具有固定效应和非线性关系的面板数据分析。它可以用于研究二项分布的计数数据,如疾病发...

Dear All, I have a question about the LR-test given at the end of xtnbreg output. Is this a test of the variance of the beta random effect being equal to zero? If so, why, when I compare the likelihoods of an xtnbreg model with it's equivalent nbreg model does (2 x) the ...

xtnbreg 示例1 文献来源 Sha等(2022)在附表A8采用了面板负二项回归(Negative binomial regression)。作者指出,由于因变量是序数变量(order variable),且均值不等于方差,因此选择负二项回归是合适的。 Sha, Y., et al. (2022).Capital market opening and green innovation——Evidence from Shanghai-Hong Kong ...
