To address the corner solution problem, I also use the panel Tobit random-effects model. I rely on a random-effects model since the panel Tobit fixed-effects model suffers from an incidental parameters problem under the small T and leads to inconsistent estimates (Neyman and Scott, 1948). The...
Stata 提供tobit命令对归并回归模型进行估计。 在命令窗口中输入help tobit命令即可查看其完整帮助文件。tobit命令的基本语法为: tobit depvar [indepvars] [if] [in] [weight],11[(#)] ul[(#)] [options] 其中ll[(#)]表示左归并,# 是左侧受限点的具体值 ;ul[(#)]表示右归并,# 是右侧受限点的具体值。

同时在经典假设条件下,通过模拟研究,比较了最小二乘回归模型,Tobit模型和断尾回归模型(truncatedregressionmodel)的估计效果,表明当因变量被截取时,Tobit模型是最适合的模型;在违反经典假设条件下,模拟研究了最大似然参数估计和半参数SCLS、CLAD估计的效果,结果证明半参数估计优于参数估计。在医学应用实例分析部分,应用...
Summary: This paper presents orthogonality conditions for censored regression models with fixed effects and lagged dependent variables. The orthogonality conditions can be used to construct method of moments estimators of the parameters of the model. Nonlinear fixed effects models are usually estimated by...
