@movinner |

Trailing moving inner product of two series (propagate NAs).

n-period moving inner product of two variables for the current and previous observations, propagating NAs.

Syntax: @movinner(x, y, n)

x: series

y: series

n integer, series

Return: series

For each observation and integer , compute the inner product of the current and previous observations of the series,

and propagating missing values (NAs).

If n is not an integer, the integer floor will be used.

Examples

show @movinner(x, y, 12)

produces a linked series of the moving inner product of the series x and y where NAs are propagated.
