locfit(formula, data, weights, cens, base, subset, geth, ..., lfproc)
formula |
Model Formula; e.g. y~x for a regression model; ~x for a
density estimation model
|
data |
Data Frame. |
weights |
Prior weights (or sample sizes) for individual observations. This is typically used where observations have unequal variance. |
cens |
Censoring indicator. 1 (or TRUE) denotes a censored observation.
0 (or FALSE) denotes uncensored.
|
base |
Baseline for local fitting. For local regression models, specifying
a base is equivalent to using y-base as the reponse. But base
also works for local likelihood.
|
subset |
Subset observations in the data frame. |
geth |
Don't use. |
... |
Other arguments to locfit.raw() (or the lfproc).
|
lfproc |
A processing function to compute the local fit. Default is
locfit.raw(). Other choices include locfit.robust(),
locfit.censor() and locfit.quasi().
|
An object with class "locfit". A standard set of methods for printing,
ploting, etc. these objects is provided.
locfit() is a model-formula based front end to locfit.raw().
