Dear all,
I am trying to plot semivariogram for my data set consisting of 1373 values. As I plotted semivariogram, trend was seen. Then I decided to remove the trend so I tried to find the trend's coefficients for Linear, quadratic and cubic using geoR package. Fortunately its worked thanks to all the R-sig_Geo users. But as i tried to plot the semivariogram of these residuals form linear, quadratic and cubic plot, the result were unusual. The plot of semivarigram for all these trends were more or less exactly the same as the semivariogram plot of original data ( trend clearly seen). Could anyone suggest me what had happened to my data. I would be thankful if i get insight in this matter.
Thanking you
Pujan
