Investigators at University of Saarland Detail Research in Stochastics and Dynamics

  2012 APR 24 - (VerticalNews.com) -- According to the authors of recent research from Saarbrucken, Germany, "We present two general results that can be used to obtain asymptotic properties for statistical functionals based on linear long-memory sequences."

  "As examples for the first one we consider L- and V-statistics, in particular tail-dependent L-statistics as well as V-statistics with unbounded kernels. As an example for the second result we consider degenerate V-statistics," wrote E. Beutner and colleagues, University of Saarland.

  The researchers concluded: "To prove these results we also establish a weak convergence result for empirical processes of linear long-memory sequences, which improves earlier ones."

  Beutner and colleagues published their study in Stochastic Processes and Their Applications (Asymptotics for statistical functionals of long-memory sequences. Stochastic Processes and Their Applications, 2012;122(3):910-929).
