residuals(object, type = c("deviance", "pearson", "working",
"response", "partial"), …)
an object of class glm
, typically the result of
a call to glm
.
the type of residuals which should be returned.
The alternatives are: "deviance"
(default), "pearson"
,
"working"
, "response"
, and "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.
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.
