summary.fsdalts: Summary Method for `fsdalts` objects

Description

summary method for class "fsdalts".

Usage

# S3 method for fsdalts
summary(object, correlation = FALSE, …)
# S3 method for summary.fsdalts
print(x, digits = max(3, getOption("digits") - 3),
     signif.stars = getOption("show.signif.stars"), …)

Arguments

object, x

an object of class "fsdalts" (or "summary.fsdalts"); usually, a result of a call to fsreg.

correlation

logical; if TRUE, the correlation matrix of the estimated parameters is returned and printed.

digits

the number of significant digits to use when printing.

signif.stars

logical indicating if “significance stars” should be printer, see printCoefmat.

…

further arguments passed to or from other methods.

Value

summary.fsdalts returns an summary.fsdalts object, whereas the print methods returns its first argument via invisible, as all print methods do.

Details

summary.fsdalts(), the S3 method, simply returns an (S3) object of class "summary.fsdalts" for which there's a print method:

print.summary.fsdalts prints summary statistics for the forward search (FS) regression estimates. While the function print.fsdalts prints only the robust estimates of the coefficients, print.summary.fsdalts will print also the regression table.

Examples

Run this code

# NOT RUN {
    data(Animals, package = "MASS")
    brain <- Animals[c(1:24, 26:25, 27:28),]
    lbrain <- log(brain)
    (fs <- fsreg(brain~body, data=lbrain, method="LTS"))
    summary(fs)

    ## compare to the result of ltsReg() from 'robustbase'
    (lts <- ltsReg(brain~body, data=lbrain))
    summary(lts)
# }
