Hi, Does anyone know a way to estimate the existence of a temporal trend (each unit of the sample is a count) by resting the possible effect of a covariate (i.e. climatic factor)? I have periodical counts of several species of waterbirds during the last 13 years and I want to know if, resting the effect of the flooded area available, there would be a temporal trend. I know the flooded area is correlated with the time series data of most of species I'm taking in account.
I had a look to time series section of the http://cran.r-project.org but I didn't find nothing on this issue. Thanks for any response _________________________________________________________________ [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
