kdplus.test R Documentation
Global test of clustering using difference in K functions
Description
kdplus.test performs a global test of clustering
for comparing cases and controls using the method of
Diggle and Chetwynd (1991). It relies on the difference
in estimated K functions.
Usage
kdplus.test(x)
Arguments
x
A kdenv object from the kdest
function.
Value
A list providing the observed test statistic
(kdplus) and the estimate p-value
pvalue.
