## 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
