@minner
Trailing moving inner product of two series (ignore NAs).
n-period moving inner product of two variables for the current and previous observations, ignoring NAs.
Syntax: @minner(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 ignoring missing values (NAs).
If n is not an integer, the integer floor will be used.
Examples
show @minner(x, y, 12)
produces a linked series of the moving inner product of the series x and y where NAs are ignored.
