Hello Idrisians !
Here is the summary of the answers I received about my problem, which I
quote here again for the posterity:
...........................
In order to compare two presence-absence predictive model I have used the
kappa statistic. I get thus two kappa values (k1 and k2), which I would
like to compare with statistical tests. The null hypoteses I would like to
test are as follows :
1� k = 0
2� k1 = k2
Who knows which test I have to use ? (and how ?)
............................
I received two answers from Bob Pontius and the illustrious J.R.Eastmann
himself. Many thanks to them !
Here are the references they gave me:

American Geographer 14(4): 345-358.
