| weighted.residuals(base) | R Documentation |
Weighted residuals are the usual residuals Ri, multiplied
by wi^0.5, where wi are the
weights as specified in lm's call.
Dropping cases with weights zero, is compatible with
lm.influence and related functions.
weighted.residuals(obj, drop0 = TRUE)
obj |
R object, typically of class lm or glm. |
drop0 |
logical. If TRUE, drop all cases with
weights == 0. |
Numeric vector of length n', where n' is the number of
of non-0 weights (drop0 = TRUE) or the number of
observations, otherwise.
