Time series

Lag operator

In time series analysis, the lag operator (L) or backshift operator (B) operates on an element of a time series to produce the previous element. For example, given some time series then for all or similarly in terms of the backshift operator B: for all . Equivalently, this definition can be represented as for all The lag operator (as well as backshift operator) can be raised to arbitrary integer powers so that and (Wikipedia).

Meaning of Lagrange multiplier

In the previous videos on Lagrange multipliers, the Lagrange multiplier itself has just been some proportionality constant that we didn't care about. Here, you can see what its real meaning is.
