Description Usage Arguments Details Value Author(s) See Also Examples

This function gives the probability of observing the ith nearest neighbour at distance c given the (i-1)th nearest neighbour at distance a, $P(d_i >= x | d_(i-1) = a)$

1	Pc_givena(i, c, a, N)

`i`	numeric, which nearest neighbour to consider
`c`	vector, the distance at which the ith NN was observed
`a`	vector, the distance at which the (i-1)th NN was observed, a <= c
`N`	numeric, size of the dataset

The probability is calculated by ranking the data and assuming that the data lie on a torus. For details see Dümcke et al. "A novel test for independence derived from an exact distribution of ith nearest neighbours" (manuscript in preparation)
