gen_weights: Generate geographic weighting matrix
In NSAPH/airpred: A Framework For Building Air Pollution Estimation Models
Description
Given two sets of points, generate a matrix of weights for the k nearest neighbors
for use in distance weighted averaging of values.
Usage
1
2
gen_weights(orig = load_site_list(), query = load_site_list(), k = 4,
threshold = 1e+05, term = 1)
Arguments
orig
the data in which the neighbors are being found
query
the data for which the neighbors need to be found
k
the number of neighbors being searched for
threshold
the maximum distance for a neighbor to be given a weight
term
the power that the distance is raised to when the weight matrix
is generated.
