Thanks for the reply. Certainly your own field is an environmental one but fairly far removed from the area that I am asking about. I'm not sure about the spatial and temporal aspects I assumed that these would be corrected for by taking into account the lack of independence between variables. As you suggest these are important considerations. 

Any way, thanks again. I shall keep on reading. I was just trying to short cut my reading a bit, and find out a bit more about Stata. I am surprised it isn't more popular in the ecological world as it seems to provide an excellent middle road between the serious hard work of SPlus or R and the less flexible systat, spss etc
