Let \((X_1, X_2, \dots, X_n)\) be a random vector which is stationary and ergodic. A sequence of pseudo observations based on this random vector are defined as \((H_n (X_1 ),\dots, H_n (X_n ))\), where \(H_n(t)\) is an estimate of the unknown function \(H(t)\) based on the sample \((X_1, X_2, \dots, X_n)\). The weak convergence of the empirical process based on the pseudo observations is derived based on some general conditions. The general results are applied to several examples including the serial copula process and the residual process in multivariate regression models. Some applications to statistics are also considered, such as the derivation of asymptotic null distribution for the test statistics in the tests of serial independence and functional hypotheses in time series.
