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

View source: R/Pc_givena.R

Description

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

Usage

1
Pc_givena(i, c, a, N)

Arguments

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

Details

The probability is calculated by ranking the data and assuming that the data lie on a torus. For details see D<c3><bc>mcke et al. "A novel test for independence derived from an exact distribution of ith nearest neighbours" (manuscript in preparation)

Value

Probability vector
