Dear Ecologgers:
I have been doing some regressions with temperature means across time series
on about 80 stations in a rather small region (less than 2 degrees lat),
contrasting before and after 1991, and not surprisingly I have found quite
significant slopes in many stations. But in trying to make out a pattern in
statistical terms I am not sure if I am breaking some rules, for one I don't
know what to do with stations where there are NO significant trends, they are
not zeros. So I can think of two approaches, multiple regression using
altitude, lat, long, even population as independant variables or use a
geostatistical model in ArcView or any other geostatistical software.
Am I breaking some holy statistical rules here ??
I would appreciate any comments since I am very far from any statistical-savy
collegue.
