cepp.weights: Compute region weights for cepp.test

Description

Compute region weights for cepp.test

Usage

cepp.weights(nn, pop, nstar)

Arguments

nn

A list of nearest neighbors produced by casewin.

pop

The population size associated with each region.

nstar

The size of the at-risk population in each window.

Value

A list with elements related to the weight each nearest neighbor region will have in the corresponding weighted sum used to compute the test statistic

Examples

# NOT RUN {
data(nydf)
coords = with(nydf, cbind(x, y))
pop = nydf$pop
# intercentroid distances
d = sp::spDists(coords)
# find smallest windows with cumulative population of
# at least n* = 1000
nn = casewin(d, pop, 1000)
# compute weights
w = cepp.weights(nn, pop, 1000)
# }
