Fast Stress Function
Description
faststress
calculates value for normalized stress with different input parameters.
Distances d are optimally scaled.
Usage
faststress(
lower = NULL,
delta = NULL,
data = NULL,
w = NULL,
z = NULL,
d = NULL
)
Arguments
lower |
an n x (n - 1 ) / 2 vector containing lower triangular part of dissimilarity matrix. |
delta |
an n by n square hollow matrix containing dissimilarities. |
data |
an n by m multivariate data matrix. |
w |
an identical sized matrix containing non-negative weights (all ones when omitted). |
z |
n by p matrix with coordinates. |
d |
distances between the rows of z, an n by n square hollow matrix containing Euclidean distances. |
Value
n.stress normalized stress value
