Tankiso,
Here is some tips:
- make your code such that cut and paste works for us; for me, the ^2
below is vanished (and interpreted as superscript right away, I don't
know why)
- you didn't test your code, as the function inv does not exist
- your code doesn't compute the kriging variance
- the c
Hi there,
good routines already exist in several R libraries for doing this. They will
save you trouble in developing bug-free and efficient code. Check out gstat and
maybe fields.
If you still want to implement kriging manually, these scripts, which I
developed for a class exercise, might be
R geo-helpers
i am new to r and would like you to help me as i am trying to go through basic
steps. I need to compute a predicted value at point (3,3) and its variance
given la set of locations and value. i want to make the code generic for any
size such that i would be able to estimate univer
