cepp.test
Compute region weights for cepp.test
cepp.weights(nn, pop, nstar)
nn |
A list of nearest neighbors produced by
|
pop |
The population size associated with each region. |
nstar |
The size of the at-risk population in each window. |
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
