## Accessing Generalized Linear Model Fits

### Description

These functions are all `methods`

for class `glm`

or
`summary.glm`

objects.

### Usage

```
## S3 method for class 'glm'
family(object, ...)
## S3 method for class 'glm'
residuals(object, type = c("deviance", "pearson", "working",
"response", "partial"), ...)
```

### Arguments

`object` |
an object of class |

`type` |
the type of residuals which should be returned.
The alternatives are: |

`...` |
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.
