Subject: Least Squares fit slope
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.
