This function computes the reachability measure for each instance
of a dataset. This result is used later to compute the Local
Outlyingness Factor.
Usage
reachability(distdata, k)
Arguments
distdata
The matrix of distances.
k
The number of neighbors.
Value
A vector.
Details
This function is strongly based on the code provided by Acuna
et. al. (2009) for the previously available dprep package.
