locfit {locfit} | R Documentation |
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()
.
