Dear list,
I want to assess if a series of cases (farms positive for a disease) are
spatially clustered by comparing them to the general population (the total
number of farms) in a given region. For that I would like to know if it is
statistically correct to use the bivariate (also known as cross) k-function,
considering cases as element 1 and general population (all farms, including
the cases) as element 2. I am using splancs (k12hat function) in R. I know
that you can do the difference of k-functions but I would like to know if
the use of the bivariate k-function is correct.
If it is statistically correct, can I conclude that the positive farms are
clustered/dispersed compared to the total population (using label
permutation)?
Thanks in advance for your help
albert
