A test of the normality assumption in ordered probit model
提出了一个拉格朗日乘子检验，用于检验有序Probit模型中的正态性假设，适用于标准模型和因变量存在删失的情况，并与人工回归技术检验进行了比较。
This paper presents a Lagrange multiplier test of the normality assumption underlying the ordered probit model. The test is presented both for the standard ordered probit model and a version in which censoring is present in the dependent variable. The test is then compared to normality tests proposed here compares favorably to tests based on artificial regression techinques.
