nearest {truh}

Nearest neighbor computation for the TRUH statistic

Description

For a given d dimensional vector \mathbf{y}, this function finds the nearest neighbor of \mathbf{y} in a n\times d matrix \mathbf{U}.

Usage

nearest(y, U, n, d)

Arguments

y

a d dimensional vector.

U

a n\times d matrix where n represents the sample size and d is the dimension of each sample.

n

the sample size.

d

dimension of each sample.

Value

1. d1 - nearest neighbor of \mathbf{y} in \mathbf{U}

2. d2 - nearest neighbor of d1 in \mathbf{U}
