lag operator
1Lag operator — In time series analysis, the lag operator or backshift operator operates on an element of a time series to produce the previous element. For example, given some time series:X= {X 1, X 2, dots },then :, L X t = X {t 1} for all ; t > 1,where L is… …
2Shift operator — In mathematics, and in particular functional analysis, the shift operators are examples of linear operators, important for their simplicity and natural occurrence. They are used in diverse areas, such as Hardy spaces, the theory of abelian… …
