Abstract: Abstract Remainder bounds in Fréchet differentiability of functionals for p-variation norms are found for empirical distribution functions. For $$ 1 \leqslant p \leqslant 2$$ the p-variation of the empirical process n1/2(Fn — F) is of order n1-p/2 in probability up to a factor (log log n) p /2. For $$ \left( {F,G} \right) \mapsto \int {FdG}$$ and for $$ \left( {F,G} \right) \mapsto F \circ {{G}^{{ - 1}}}$$ this yields nearly optimal remainder bounds. Also, p-variation gives new proofs for the asymptotic distributions of the Cramér-von Mises-Rosenblatt and Watson two-sample statistics when the two sample sizes m, n go to infinity arbitarily.
