summary.glmrob

Summarizing Robust Fits of Generalized Linear Models

Description

The summary method for class "glmrob" summarizes robust fits of (currently only discrete) generalized linear models.

Usage

## S3 method for class 'glmrob'
summary(object, correlation = FALSE, symbolic.cor = FALSE, ...)
## S3 method for class 'glmrob'
vcov(object, ...)

## S3 method for class 'summary.glmrob'
print(x, digits = max(3, getOption("digits") - 3),
      symbolic.cor = x$symbolic.cor,
      signif.stars = getOption("show.signif.stars"), ...)

Arguments

`object`	an object of class `"glmrob"`, usually, a result of a call to `glmrob`.
`correlation`	logical; if `TRUE`, the correlation matrix of the estimated parameters is returned and printed.
`symbolic.cor`	logical. If `TRUE`, print the correlations in a symbolic form (see `symnum`) rather than as numbers.
`...`	further arguments passed to or from other methods.
`x`	an object of class `"summary.glrob"`.
`digits`	the number of digits to use for printing.
`signif.stars`	logical indicating if the P-values should be visualized by so called “significance stars”.

Details

summary.glmrob returns an object of class "summary.glmrob".

Its print() method tries to be smart about formatting the coefficients, standard errors, etc, and gives “significance stars” if signif.stars is TRUE (as per default when options where not changed).

Value

The function summary.glmrob computes and returns a list of summary statistics of the robustly fitted linear model given in object. The following elements are in the list:

Examples

data(epilepsy)
Rmod <- glmrob(Ysum ~ Age10 + Base4*Trt, family = poisson,
               data = epilepsy, method= "Mqle")
ss <- summary(Rmod)
ss ## calls print.summary.glmrob()
str(ss) ## internal STRucture of summary object
