Hi Thierry,

thank yo for the reply.

I did find that post by Edzer also, but thought that perhaps someone  
may have done something since.
If I remember, Edzer's reply post was from 2007. I should have maybe  
mentioned that on my post.

So, it appears that FK has not been implemented in R. i wonder why...?

If I understand correctly, it should not be too difficult to do if you  
already have the kriging algorithm.
It seems that one just sets the constraint on the kriging weights to 0  
rather than 1. Does this sound right?

Cheers
Raphael

Dear Raphael,

Using RSiteSearch("factorial kriging") I found this post from Edzer:

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
