Subject:      Least Squares fit slope

Hello

Am wanting to take a set of production data measurements and determine
the numeric slope for a least squares fit line to determine if a
particular location is improving or declining over the selected time
period.  An Excel equivalent function would be LINEST or SLOPE.

Data looks like so

LOCATION  DATE       MEASURE
XXX       01Jan2000   4800
YYY       01Jan2000   4126
XXX       02Jan2000   4765
YYY       02Jan2000   4360
XXX       03Jan2000   4915
.....

What I am looking for is a value that tells me for each location if
their measure has improved and to what degree.

I am sure SAS can do it, I just can't figure out how.
Thanks
Ben
