WebApr 1, 2024 · Guyon (1995) and Karácsony (2006) just refer to the simple application of the Cramér–Wold device and in particular do not discuss the issue of whether a limiting covariance matrix exists or not. To be on firm ground, a Cramér–Wold type result covering the case with no limiting covariance matrix seems missing. WebWold device shown below implies that the distribution of X is uniquely identi ed by E(ei X). Since the characteristic function of X is ’(t) = E(eit X) = E(ei P tkXk); where t = (t1;:::;td) 2 …
