# glm.summaries

##### Accessing Generalized Linear Model Fits

These functions are all `methods`

for class `glm`

or
`summary.glm`

objects.

- Keywords
- models, regression

##### Usage

```
"family"(object, ...)
"residuals"(object, type = c("deviance", "pearson", "working", "response", "partial"), ...)
```

##### Arguments

- object
- an object of class
`glm`

, typically the result of a call to`glm`

. - type
- the type of residuals which should be returned.
The alternatives are:
`"deviance"`

(default),`"pearson"`

,`"working"`

,`"response"`

, and`"partial"`

. - ...
- further arguments passed to or from other methods.

##### Details

The references define the types of residuals: Davison & Snell is a good reference for the usages of each.

The partial residuals are a matrix of working residuals, with each column formed by omitting a term from the model.

How `residuals`

treats cases with missing values in the original
fit is determined by the `na.action`

argument of that fit.
If `na.action = na.omit`

omitted cases will not appear in the
residuals, whereas if `na.action = na.exclude`

they will appear,
with residual value `NA`

. See also `naresid`

.

For fits done with `y = FALSE`

the response values are computed
from other components.
