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.
