persp.qdm

object of class 'qdm'. See <code><a rd-options="" href="/link/qdm?package=qdm&version=0.1-0" data-mini-rdoc="qdm::qdm">qdm</a></code>.

the color(s) of the surface facets.  Transparent colours are
        ignored. This is recycled to the (nx-1)(ny-1) facets.

Defaults to zlim=c(0,1) since probabilities are plotted.

zlim

angles defining the viewing direction. 'theta' gives the
        azimuthal direction and 'phi' the colatitude.

theta, phi

titles for the axes. N.B. These must be character
        strings; expressions are not accepted. Numbers will be
        coerced to character strings.

xlab, ylab, zlab

additional graphical parameters (see 'par').


  Draws a perspective plot of the predictions of a Quadrilateral
  Dissimilarity Model fitted with <code><a rd-options="" href="/link/qdm?package=qdm&version=0.1-0" data-mini-rdoc="qdm::qdm">qdm</a></code>.


This package provides different specifications of a Quadrilateral
Dissimilarity Model which can be used to fit same-different judgments
in order to get a predicted matrix that satisfies regular minimality
[Colonius & Dzhafarov, 2006, Measurement and representations of
sensations, Erlbaum]. From such a matrix, Fechnerian distances can be
computed.
