Abstrakt: A method of extending the classical ARIMA and GARCH models to the continuous and nonlinear cases is considered. Stochastic functional differential equations, which are a natural generalization of the sums of independent random variables, are considered extended models. Along with the new model, a relevant optimization problem of estimating model parameters is considered, and the non-parametric problem is reduced to a parametric one. The new model was tested on real data, and the forecast results were compared with classical models. [ABSTRACT FROM AUTHOR]
