Summary Method for MCD objects
Description
summary method for class "mcd".
Usage
## S3 method for class 'mcd'
summary(object, ...)
## S3 method for class 'summary.mcd'
print(x, digits = max(3, getOption("digits") - 3),
print.gap = 2, ...)
Arguments
object, x |
an object of class |
digits |
the number of significant digits to use when printing. |
print.gap |
number of horizontal spaces between numbers; see also
|
... |
further arguments passed to or from other methods. |
Details
summary.mcd(), the S3 method, simply returns an (S3) object of
class "summary.mcd" for which there's a
print method:
print.summary.mcd prints summary statistics for the weighted covariance
matrix and location estimates with weights based on MCD estimates.
While the function print.mcd prints only the robust estimates
of the location and the covariance matrix, print.summary.mcd will
print also the correlation matrix (if requested in the call to
covMcd with cor=TRUE), the eigenvalues of the covariance
or the correlation matrix and the robust (“Mahalanobis”) distances.
Value
summary.mcd returns an summary.mcd object, whereas the
print methods returns its first argument via
invisible, as all print methods do.
