In other words, tobit regression is used when the dependent variable has a lower or upper limit, and the observed values are either below or above those limits. To explain the tobit maximum likelihood estimation method in Stata, we will use a hypothetical example. Let's say we want to ...
Tobit模型属于截尾回归模型, 最早是由James Tobit提出的, 又被称为截断式回归模型 (Censored Regression Model) 。由于高校科技投入产出技术效率值介于0~1之间, 如采用最小二乘法, 其参数估计会有严重的偏差, 因此, 当被解释变量受到限制时, 采用Tobit模型进行分析更为有效[8]。

I have written a Stata ado file to implement this estimation procedure. It runs a regression and calculates standard errors which account for two dimensions of within cluster correlation. The variables which record the two dimensions (e.g. a firm identifier and a time identifier) are specified ...
Tobit regression (RE) Description Description DDeessccrriippttiioonn xttobit fits random-effects tobit models. There is no command for a parametric conditional fixedeffects model, as there does not exist a sufficient statistic allowing the fixed effects to be conditioned out of the likelihood. ...
