backmigrate: Sample from Parental Locations
In petrelharp/landsim: Simulate Populations on Landscapes
Description
Usage
Arguments
Value
Description
This takes a set of locations and a nonnegative weighting vector,
and samples from the time-reversed migration probabilities, weighted by the weights.
Usage
1
backmigrate(x, migration, weights)
Arguments
x
A vector of locations (indices).
migration
The migration object.
weights
A nonnegative vector of weights.
Value
A vector of locations of the same form as x.
If the probability of migrating from i to j is M[i,j], then a sample at j will choose i
with probability equal to weights[i] M[i,j]/sum(weights*M[,j]).
