Description

ENNreg_init returns initial parameter values for the ENNreg model.

Usage

ENNreg_init(X, y, K, nstart = 100, c = 1)

Value

An object of class "ENNreg", which can be passed to function ENNreg.

Arguments

X

Input matrix of size n x p, where n is the number of objects and p the number of attributes.

y

Vector of length n containing observations of the response variable.

K

Number of prototypes.

nstart

Number of random starts of the k-means algorithm (default: 100)

c
