In the statistical analysis of time series, autoregressive–moving-average (ARMA) models provide a parsimonious description of a (weakly) stationary stochastic process in terms of two polynomials, one for the autoregression (AR) and the second for the moving average (MA). The general ARMA model was … See more The notation AR(p) refers to the autoregressive model of order p. The AR(p) model is written as $${\displaystyle X_{t}=\sum _{i=1}^{p}\varphi _{i}X_{t-i}+\varepsilon _{t}}$$ See more In some texts the models will be specified in terms of the lag operator L. In these terms then the AR(p) model is given by See more Choosing p and q Finding appropriate values of p and q in the ARMA(p,q) model can be facilitated by plotting the partial autocorrelation functions for an estimate of p, and likewise using the autocorrelation functions for an estimate of q. … See more The notation MA(q) refers to the moving average model of order q: where the See more The notation ARMA(p, q) refers to the model with p autoregressive terms and q moving-average terms.
