stepArchetypesRawData_robust {adamethods}

Archetype algorithm to raw data with the robust Frobenius norm

Description

This is a slight modification of stepArchetypesRawData to use the archetype algorithm with the robust Frobenius norm.

Usage

stepArchetypesRawData_robust(data, numArch, numRep = 3, 
                             verbose = TRUE, saveHistory = FALSE, prob)

Arguments

data

Data to obtain archetypes.

numArch

Number of archetypes to compute, from 1 to numArch.

numRep

For each numArch, run the archetype algorithm numRep times.

verbose

If TRUE, the progress during execution is shown.

saveHistory

Save execution steps.

prob

Probability with values in [0,1].

Value

A list with the archetypes.
