Empirical-process convergence conjecture for pseudo-observations
Empirical-process convergence conjecture for pseudo-observations
Let be the distribution function of the transformed observations, let be the empirical distribution function based on the rank-based pseudo-observations, and define
Let be a standard Wiener process and let be a stochastic process on . Empirical-process convergence conjecture. As , converges weakly in to
where the sample paths of are almost surely locally Lipschitz continuous at . Moreover, on a possibly enriched probability space containing the data and , there exists such that
This high-level conjecture is introduced to analyze the asymptotic behavior of the kernel density estimator based on dependent rank-based pseudo-observations. The weak convergence and coupling-rate assertion provide the empirical-process input needed for that analysis; the source gives no evidence that the conjecture has been resolved.
