2.1 模型估计的实现 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,# ...
两部模型(two-part model)与Tobit模型有很大的相似之处,也是研究受限因变量问题的模型;但是这两种模型在模型结构形式、估计方法、假设条件等方面也存在一定的区别。Tobit模型的估计方法与模型结构形式有密切关系,不同类型的模型估计方法存在较大的差异,本文按照三种属性特征对Tobit模型进行了分类。 对于被解释变量的某些...
The Tobit model was first proposed by Tobin (1958) using the maximum likelihood estimator. The Tobit model is specified as Y⁎ is modeled as a latent variable, as opposed to the actually observed outcome Y. Accordingly, when Y⁎ > 0, Y is observed and otherwise Y is 0. f(Ci) ...

described in [XT] xt, we fit a random-effects tobit model of adjusted (log) wages. We use the ul() option to impose an upper limit on the recorded log of wages. We use the intpoints(25) option to increase the number of integrationpointsto25 from12,which aidsconvergenceofthis model....

Step 2: Model Specification Next, we need to specify the tobit model in Stata. We can do this by using the "tobit" command followed by the dependent variable and the independent variables. For example, if our dependent variable is "income" and our independent variables are "education," "ag...
The Tobit model's capability to address the skewness in the dependent variable's distribution is noteworthy. This feature makes it particularly suitable for scenarios where the dependent variable's values are not fully observable, providing a more accurate representation of the underlying ...
