Description
Computes Tukey's biweight objective function (scale) corresponding
with the Mahalanobis distances x.
Usage
sestck(x, start, c, k, tol)
Arguments
x |
a vector of data corresponds to the Mahalanobis distances. |
start |
indicates the initial scale if different from zero, else scale will be estimated by the median. |
c |
Tukey's biweight constant. |
k |
the tuning constant for the multivariate S-estimator of location and covariance. |
tol |
indicates the tolerance value of the iteration algorithm. |
