%description
Flexible multidimensional scaling (MDS) methods and extensions to the
package 'smacof'. This package contains various functions, wrappers,
methods and classes for fitting, plotting and displaying a large number of
different flexible MDS models. These are: Torgerson scaling (Torgerson,
1958, ISBN:978-0471879459) with powers, Sammon mapping (Sammon, 1969,
<doi:10.1109/T-C.1969.222678>) with ratio and interval optimal scaling,
Multiscale MDS (Ramsay, 1977, <doi:10.1007/BF02294052>) with ratio and
interval optimal scaling, s-stress MDS (ALSCAL; Takane, Young & De Leeuw,
1977, <doi:10.1007/BF02293745>) with ratio and interval optimal scaling,
elastic scaling (McGee, 1966, <doi:10.1111/j.2044-8317.1966.tb00367.x>)
with ratio and interval optimal scaling, r-stress MDS (De Leeuw, Groenen &
Mair, 2016, <https://rpubs.com/deleeuw/142619>) with ratio, interval,
splines and nonmetric optimal scaling, power-stress MDS (POST-MDS; Buja &
Swayne, 2002 <doi:10.1007/s00357-001-0031-0>) with ratio and interval
optimal scaling, restricted power-stress (Rusch, Mair & Hornik, 2021,
<doi:10.1080/10618600.2020.1869027>) with ratio and interval optimal
scaling, approximate power-stress with ratio optimal scaling (Rusch, Mair
& Hornik, 2021, <doi:10.1080/10618600.2020.1869027>), Box-Cox MDS (Chen &
Buja, 2013, <https://jmlr.org/papers/v14/chen13a.html>), local MDS (Chen &
Buja, 2009, <doi:10.1198/jasa.2009.0111>), curvilinear component analysis
(Demartines & Herault, 1997, <doi:10.1109/72.554199>), curvilinear
distance analysis (Lee, Lendasse & Verleysen, 2004,
<doi:10.1016/j.neucom.2004.01.007>), nonlinear MDS with optimal
dissimilarity powers functions (De Leeuw, 2024,
<https://github.com/deleeuw/smacofManual/blob/main/smacofPO(power)/smacofPO.pdf>),
sparsified (power) MDS and sparsified multidimensional (power) distance
analysis aka extended curvilinear (power) component analysis and extended
curvilinear (power) distance analysis (Rusch, 2024,
<doi:10.57938/355bf835-ddb7-42f4-8b85-129799fc240e>). Some functions are
suitably flexible to allow any other sensible combination of explicit
power transformations for weights, distances and input proximities with
implicit ratio, interval, splines or nonmetric optimal scaling of the
input proximities. Most functions use a Majorization-Minimization
algorithm. Currently the methods are only available for one-mode two-way
data (symmetric dissimilarity matrices).
