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.
