资源简介:
A preliminary investigation of two specification error problems in truncated dependent variable models is reported. It is shown that heteroscedasticity in a tobit model results in biased estimates when the model is misspecified. This differs from the OLS model where estimates are still consistent
本文报道了针对截断因变量模型中两类设定误差问题的初步探究。研究表明,当托比特模型(Tobit model)设定错误时,其内部存在的异方差性会导致估计结果出现偏倚。这与普通最小二乘法(OLS)模型不同,后者的估计结果仍保持一致性。
