摘要

A k-lag autocopula is coupled with a bivariate joint distribution function of the bivariate random vector (Y_t, Y_(t-k)), where k is the time lag of the values of the random variables that generate time series. In the contribution we utilize the idea of the autocopulas, used for testing of the heteroscedasticity in AR-ARCH model. We apply the test as an alternative approach to testing of the linearity against SETAR type nonlinearity and the remaining nonlinearity in the SETAR models.
