Autoregressive models its mean, variance, autocovariance, autocorrelation function.
The AR model is a kind of random procedure that is used frequently to model and expect several kinds of normal occurrences. The AR model is one of a group of linear expectation methods that crack to guess an output of a system based on the previous outputs.
