Series Trend Analysis Operation
1. Select the type of trend or significance procedure.
-- Linearity calculates the R2 of the least square correlation of the series with a linear trend.
-- Linear correlation calculates the R of the least square correlation of the series with a linear trend.
-- Linear trend calculates the intercept and slope of the least square correlation of the series with a linear trend.
-- Median trend calculates the non-parametric Theil-Sen slope and intercept of the series.
-- Monotonic trend calculates the non-parametric Mann-Kendall Tau correlation coefficient.
-- Mann-Kendall significance calculates the z and p values of the significance of the monotonic trend.
2. Select the input series. It is recommended to run this analysis on anomalies.
3. Depending on the procedure chosen, indicate whether the data represents angles (from 0 to 360º).
4. Indicate whether to use a mask file and specify its name.
-- If a mask was included in the project, the name will be input automatically.
5. Enter an output prefix.
6. Click Run.
The results of the analysis can be viewed from the Explore Trends panel with the interannual series option.
