两个内生变量情形下结构参数 t 统计量的分布AI 解读

In this article we study the exact finite sample distribution function of a t-statistic that can be used to test hypotheses and construct confidence intervals for structural coefficients in simultaneous equations models. It is shown that the exact distribution function is equal to Student's t-distribution when one of its parameters is zero and converges to Student's t-distribution function as another of its parameters increases without bound. Computations of the exact…

结构系数估计量的精确分布AI 解读

The distribution studied is that of an estimator of a structural parameter appearing in a system of linear simultaneous equations. The relationship between the bias and the true parameter value is analysed and the bias is tabulated for selected values of the parameters of the distribution. It is also shown that the estimator possesses finite moments up to order v where v is the number of overidentifying restrictions and that the estimator converges to the true parameter…
