An ARIMA ( p, d, q) process expresses this polynomial factorisation property with p = p'−d, and is given by: and thus can be thought as a particular case of an ARMA ( p+d, q) process having the autoregressive polynomial with d unit roots. Visualizza altro In statistics and econometrics, and in particular in time series analysis, an autoregressive integrated moving average (ARIMA) model is a generalization of an autoregressive moving average (ARMA) model. To … Visualizza altro A stationary time series's properties do not depend on the time at which the series is observed. Specifically, for a wide-sense stationary time series, the mean and the variance/autocovariance keep constant over time.
