Dear all,
I d`appreciate your help in two points. Firstly, the data I deal with are a 
series of circle shaped sample areas, each of them consisting of 25-35 basic 
units. The data subject to geostatistical analysis are average values per each 
sample area assigned to the center of the area. The first question relates to 
variogram regularisation. Since the number of basic units (in fact trees in the 
sample area) is unequal, how the regularisation should be accomplished in this 
case? As I read in a literature, the lenght of core is often mentioned in this 
regard to produce regularized variogram, but I am not just clear how is it in 
my case. 
The second point is something like proportional effect. The mean values per 
each area increases along with variability (st.dev vs mean is R=0.76). How this 
affects the variography and kriging? I might mathmematicaly stabilize the 
variability, but I am afraid of spoiling the data. Besides, this phenomenon has 
certain interpretation in forest science. Is there some specific geostatistical 
treatment of this? 
Thank you very much 
Regards
Tomas
