estimate_lambda

Estimate lambda values

Internal function to estimate values of lambda needed for MCMC_simulation and prior probability of k clusters/anti-clusters for k=0,...,J

estimate_lambda(n.sim, J, prior.z, overlap, pi0)

`n.sim`	number of importance sampling iterations
`J`	maximum number of clusters/anti-clusters to consider
`prior.z`	prior probability of each single zone
`overlap`	output of `create_geo_objects`: list with two elements: `presence` which lists for each area all the single zones it is present in and `cluster_list` for each single zone its component areas
`pi0`	prior probability of no clusters

estimates of lambda and prior.j
