WebFeb 12, 2024 · This test is useful to judge whether causalities exist between two variables over time. However, it is unable to assess whether the underlying causalities are positive or negative. As aforementioned, the sup Wald statistic is the maximum value of a sequence of Wald statistics, so there is a f * that satisfy the following equation. WebApr 1, 2024 · Additionally, the corresponding estimate of the sup-Wald test is supW T = sup sup W T (τ i). Following this stride, De Long (1981) proposes that the Gaussian random walk could also be used to estimate the critical value of the sup-Wald test, so as to capture the causal relationship of each quantile range. The QGC test is not only permitted to ...

Critical values are given for degrees of freedom p=1 20. The critical values for p=8 are not correct (except for 0 =5). They are too small. For the common choice of 0 =15, they yield null rejection rates of .162, .084, and .016 for nominal sizes .10, .05, and .01, respectively (based on
