WebAn auto-regressive model predicts time series values by a linear combination of its past values. It assumes that the time series shows auto-correlation and that the past value is correlated with the current value. The model will be able to predict the next sample in the time series when the system works properly. can ibhWebA time series is considered to be one of the leaders if its rise or fall impacts the behavior of many other time series.
