Web15 mar 2024 · Arima is short for Auto-Regressive Integrated Moving Average, which is a forecasting algorithm based on the assumption that previous values carry inherent information and can be used to predict future values. We can develop a predictive model to predict xₜ given past values., formally denoted as the following: p (xₜ xₜ₋₁, … ,x₁)

An ARIMA (0, 0, 0) model is a white noise model. An ARIMA (0, 1, 2) model is a Damped Holt's model. An ARIMA (0, 1, 1) model without constant is a basic exponential smoothing model. [9] An ARIMA (0, 2, 2) model is given by — which is equivalent to Holt's linear method with additive errors, or … 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 The explicit identification of the factorization of the autoregression polynomial into factors as above can be extended to other cases, firstly to apply to the moving average polynomial and secondly to include other special factors. For example, … Visualizza altro The order p and q can be determined using the sample autocorrelation function (ACF), partial autocorrelation function (PACF), … Visualizza altro Given time series data Xt where t is an integer index and the Xt are real numbers, an $${\displaystyle {\text{ARIMA}}(p',q)}$$ model is given by or equivalently by 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/ Visualizza altro Some well-known special cases arise naturally or are mathematically equivalent to other popular forecasting models.
