In the last article, we learned about two algorithms to estimate the AR(p) process coefficients: the Yale-Walker ... Webb8 nov. 2024 · One more indication of the MA process is that the PACF plot decays more slowly. Similar to selecting for the AR model, in order to select the appropriate order for the MA model, we need to analyze all spikes higher than the blue area. In that sense, from the image below, we can try using or . 5.3. ARMA Definition

Using them and the following formula (from Wei (2005) P. 15) you can calculate the partial autocorrelations. Furthermore, you can calculate the PACF as regression coefficients regressing Z t + k on its k lagged variables Z t + k − 1, Z t + k − 2 …, Z t. Share Cite Improve this answer Follow
Webb27 okt. 2015 · An MA ( q) process is just a linear combination of q i.i.d. errors. A linear combination of a process that is not weakly stationary will in general not be weakly stationary itself. Therefore, an MA process based on non -weakly-stationary errors will not be weakly stationary. Hence, MA process is not weakly stationary in general. Webbq-Gaussian processes are deformations of the usual Gaussian distribution. There are several different versions of this; here we treat a multivariate deformation, also addressed as q-Gaussian process, arising from free probability theory and corresponding to deformations of the canonical commutation relations.
