STOPS versions of smacofSphere models

Description

STOPS versions of smacofSphere models

Usage

stop_smacofSphere(dis, theta = c(1, 1), ndim = 2, weightmat = NULL,
  init = NULL, ..., stressweight = 1, structures = c("cclusteredness",
  "clinearity", "cdependence", "cmanifoldness", "cassociation",
  "cnonmonotonicity", "cfunctionality", "ccomplexity", "cfaithfulness",
  "cregularity"), strucweight = rep(1/length(structures), length(structures)),
  strucpars, verbose = 0, type = c("additive", "multiplicative"))

Arguments

dis

numeric matrix or dist object of a matrix of proximities

theta

the theta vector of powers; this is either a scalar of the lambda transformation for the observed proximities, or a vector where the first is the kappa argument for the fitted distances (here internally fixed to 1) and the second the lambda argument and the third the nu argument (here internally fixed to 1). Defaults to 1 1 1

ndim

number of dimensions of the target space

weightmat

(optional) a matrix of nonnegative weights

init

(optional) initial configuration

...

additional arguments to be passed to the fitting procedure

stressweight

weight to be used for the fit measure; defaults to 1

structures

which structuredness indices to be included in the loss

strucweight

weight to be used for the structuredness indices; ; defaults to 1/#number of structures

strucpars

the parameters for the structuredness indices

verbose

numeric value hat prints information on the fitting process; >2 is extremely verbose

type

How to construct the target function for the multi objective optimization? Either 'additive' (default) or 'multiplicative'

Value

A list with the components
