WebWhere we assume a common α= ρ−1 but allow the lag order for the difference terms, ρi to vary across cross-sections. The null and alternative hypotheses for the tests may be written as H 0: α= 0 H 1: α< 0 so under the null hypothesis, there is a unit root, while under the alternative, there is no unit root.

Web(ii) Apply the augmented Dickey–Fuller (ADF) test to each individual series and normalize the disturbances. For illustration, we use model 5. The ADF regression ˜yi,t ‹ri yi,tÿ1 ⁄ Xpi j‹1 Łij˜yi,tÿj ⁄Æi ⁄åi,t (1) is equivalent to performing two auxiliary regressions of ˜yit and yi,tÿ1 on the remaining variables in equation (1). Web总结. Fisher's 精确检验，用来检验一次随机实验的结果是否支持对于某个随机实验的假设，当测试结果出现小概率事件则认定原有假设不被支持，理论源于超几何分布，以p_value作为检测值，计算的p-value越小，表示越远离零假设。. 在实际计算当中又分为单边检验 ... immigration psychological assessment
