weighted.residuals(obj, drop0 = TRUE)
obj
|
R object, typically of class lm or glm.
|
drop0
|
logical. If TRUE, drop all cases with
weights == 0.
|
weights as specified in lm's call.
Dropping cases with weights zero, is compatible with
lm.influence and related functions.
drop0 = TRUE) or the number of
observations, otherwise.residuals,lm.influence, etc.
