essReference {intrinsicDimension}

ESS Reference Values

Description

Reference values for the ESS dimension estimation method

Usage

essReference(ver, d, maxdim, mindim=1)

Arguments

ver

Possible values: 'a' and 'b'. See Johnsson et al. (2015).

d

For ver = 'a', any value of d is possible, for ver = 'b', only d = 1 is supported.

maxdim

The largest dimension for which reference values should be computed.

mindim

The smallest dimension for which reference values should be computed.

Details

The ESS reference values are used by the ESS algorithm (essLocalDimEst) to compute the final dimension estimate.

Value

A vector of length maxdim-(mindim-1), where each slot represents the reference value.
