maxi

up to which ith nearest neighbour to consider

Value

This function returns an object of class htest with:

statistic

The value of the statistic

p.value

p-value of the test

Examples

set.seed(10)
xylist = generate.benchmark.data(7,.3,100)
x = runif(100)
novelTest.chisq(x,xylist$y,maxi=20)
novelTest.chisq(xylist$x,xylist$y,maxi=20)
