cepp.weights: Compute region weights for 'cepp.test'

In jpfrench81/smerc: Statistical Methods for Regional Counts

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

data(nydf)
coords <- with(nydf, cbind(x, y))
pop <- nydf$pop
# intercentroid distances
d <- gedist(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)
