      I think if your data is normally distributed, your kriging variance is normally distributed.

      You will have higher kriging variances for sam ples which have higher variogram values

      Dear List:


      Got two questions about Kriging variance, If i have an area of interest, many known points and I want to use kriging to estimate grid points all over the area.  


      1. Suppose stationarity, should kriging variance following a normal distribution? or should it be random?


      2. Besides configuration of known samples, what are the other factors that may affect the magnitude of kriging variance at a give location?



      Thank you very much
