GEOSTATS: how to detect a trend ?
- View SourceHello !
A beginners-question again : I have have data which I want to interpolate,
but before I would like to know, if there is a spatial trend. I make plots
data versus x-coordinate and data versus y-coordinate and cannot detect an
obvious trend. then I generate a trend-plain in the programm gstat and this
plain has a spatial trend ...
But how to know if the trend is significant ? Can I see this on the
prediction-variance of the trend-plain or are there other test like a
Men-Kendall-Test for spatial trends ?
Thanks for your help
