ParetoRadius: ParetoRadius for distributions

Description Usage Arguments Details Value Note Author(s) References

View source: R/ParetoRadius.R

Description

Calculation of the ParetoRadius i.e. the 18 percentiles of all mutual Euclidian distances in data.

Usage

1
2
ParetoRadius(Data, maximumNrSamples = 10000,
  plotDistancePercentiles = FALSE)

Arguments

Data

numeric data vector

maximumNrSamples

Optional, numeric. Maximum number for which the distance calculation can be done. 1000 by default.

plotDistancePercentiles

Optional, logical. If TRUE, a plot of the percentiles of distances is produced. FALSE by default.

Details

The Pareto-radius of the hyperspheres is derived from the optimization of information for minimal set size. ParetoRadius() is a kernel density estimation for variable intervals. It works only on Data without missing values (NA) or NaN. In other cases, please use ParetoDensityEstimation directly.

Value

numeric value, the Pareto radius.

Note

This the second version of the function prior available in AdaptGauss.

For larger datasets the quantile_c() function is used instead of quantile in R which was programmed by Dirk Eddelbuettel on Jun 6 and taken by the author from https://github.com/RcppCore/Rcpp/issues/967.
