One \(H_0\) test in four different rejections. a The existing method considers a rejection in the weakest collegiality. b One dimension of rejection that considers \(\lnot (s^{(2)}=0)\), where \(\lnot (s =0)\) denotes ‘the rejection of \(s=0\)’. c The other dimension of rejection that considers \(\lnot (s^{(1)}=0)\). d Two dimensions of rejection that considers \(\lnot (s^{(1)}=0)\) & \(\lnot (s^{(2)}=0)\) jointly, i.e. a rejection in the strongest collegiality
