Hi, I am trying to calculate trends in my climatic time series, using the "Zyp" package. Initially, I tried with my daily data (I have daily rainfall data of 30 years) but then both the Zhang method and Yue-Pilon method yielded unrealistic results. The trend estimates were zero and so were the confidence limit bounds. But I guess, that is because the noise in the daily data. So, I converted my time series to annual data and now I see the attached output. I see that there is a positive trend, but my question is is this trend significant at 95% confidence interval? I suspect no because the confidence interval contains zero? Can anyone please confirm?
I also attached the autocorrelation plot of the original time series. Thanks, Som -- *Somsubhra Chattopadhyay* Graduate Research Assistant Biosystems and Agricultural Engineering Department University of Kentucky, Lexington, KY 40546 Email: schatto...@uky.edu Cell: 9198026951
