WebIn time series analysis, the moving-average model (MA model), also known as moving-average process, is a common approach for modeling univariate time series. The moving-average model specifies that the output variable depends linearly on the current and various past values of a stochastic (imperfectly predictable) term. WebSep 29, 2024 · This model is used for integer-valued time series analysis. Also, the INGARCH model with Poisson deviates is an analogue of the GARCH model with normal deviates. X t and F t-1 are integer-valued time series data at time t and information set up to time t-1, and then the INGARCH(p,q) model is represented by a Poisson distribution as follows .
