How to include a time trend in a regression?

[PERRY]

What is the instruction to include a time trend in a regression?

Thank you

SET TREND = T

and include TREND in the regressor list.

Also, note that we do discuss this in the Introduction to RATS (assuming you have version 8--it should be covered in Getting Started in older versions). See pages 53-54 of the Introduction (or just look up "Trend series" in the Index to the Introduction).
