Creating string of date of last observation minus 1

Postby zsaijid » Mon Jun 03, 2019 11:10 am

Hello,

What is the easiest way to return date of last observation minus 1. (i.e. if my data series goes through 2019m4, i want 2019m3)

Thanks

Penultimate observation of workfile, or penultimate non-NA value of a particular series, or last non-NA value of a particular series minus one observation?

The penultimate observation of a data series, but the date value. So if {%x}.@last gives you last date of that series and I want the prenultimate date.

Doesn't matter if the prenultimate value is NA

Code: Select all

@otod(@ilast(x)-1)

where X is the series.
