Accessing Generalized Linear Model Fits
These functions are all
methods for class
"family"(object, ...)"residuals"(object, type = c("deviance", "pearson", "working", "response", "partial"), ...)
- an object of class
glm, typically the result of a call to
- the type of residuals which should be returned.
The alternatives are:
"partial". Can be abbreviated.
- further arguments passed to or from other methods.
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.
residuals treats cases with missing values in the original
fit is determined by the
na.action argument of that fit.
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
For fits done with
y = FALSE the response values are computed
from other components.
