stop_flexsmacof {stops}R Documentation

STOPS versions of flexsmacof models (models with a parametric f() transformation to be determined)

Description

STOPS versions of flexsmacof models (models with a parametric f() transformation to be determined)

Usage

stop_flexsmacof(dis, transformation = mkPower2, theta = c(1, 1), ndim = 2,
  weightmat = NULL, init = NULL, ..., structures = c("clusteredness",
  "linearity", "cdependence", "cmanifoldness", "cassociation",
  "cnonmonotonicity", "cfunctionality", "ccomplexity", "cfaithfulness",
  "cregularity"), stressweight = 1, strucweight = rep(1/length(structures),
  length(structures)), strucpars, verbose = 0)

Arguments

dis

numeric matrix or dist object of a matrix of proximities

transformation

function to transform the proximities or distances; need to be parameterized by theta

theta

the theta vector of transformations

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

structures

which structuredness indices to be included in the loss

stressweight

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

strucweight

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

strucpars

strucpars

verbose

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

Value

A list with the components
