A Consistent Conditional Moment Test of Functional Form
证明任何非线性回归模型函数形式的条件矩检验都可转化为卡方检验，该检验对模型设定错误具有一致性。
In this paper, it will be shown that any conditional moment test of functional form of nonlinear regression models can be converted into a chi-square test that is consistent against all deviations from the null hypothesis that the model represents the conditional expectation of the dependent variable relative to the vector of regressors.
