@movsum
Trailing moving sums (propagate NAs).
n-period trailing moving sums, propagating NAs.
Syntax: @movsum(x, n)
x: series
n integer, series
Return: series
For each observation and integer , compute the sum () using 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 @movsum(x, 12)
produces a linked series of the moving sum of the series x where NAs are propagated.
