1193RE: GEOSTATS: Test for spatial randomness
- Feb 15, 1999I suppose what you want is to see if each observation in independent in
space and time, or whether they are clustered. You can use variography on
binary data (as described in Isaaks and Srivastava) to see if there is
dependence, as long as you know the points in Euclidean space and time where
the dolphins appeared. There are also tests of significance, but I'm not
well-versed in them. As others have noted, if dolphins do behave randomly
and independently then we will have to fundamentally alter our world view.
