Hello All,
I am having problem with semivariogram.
Say, there is three points (1,4),(2,1),(3,3). The results at this points are 50, 40 ,25.
I want to use kriging method to find the result at (2,2) point.
For this reason i will have to get the gamma values So that i can make a equation set like...
g1t,g2t, g3t indicating the gamma value corresponding to 1,2,3 point with the target point.


From here i need to get w1,w2 and w3.
For gamma value, spherical semivariogram can be used.(i think so, not sure)


My problem is that i dont know how to get c0, c1 and a?
If anyone can help me, it will be really helpful for me. Thank you.
