scb {locfit}  R Documentation 
scb
is implemented as a frontend to locfit
,
to compute simultaneous confidence bands using the tube formula
method and extensions, based on Sun and Loader (1994).
Some examples can also be found at http://sun.cwru.edu/~jiayang/sci3.html.
scb(x, ..., type=1)
x 
A numeric vector or matrix of predictors (as in locfit.raw ),
or a model formula (as in locfit ).

... 
Additional arguments to locfit.raw ; e.g.,
mg , flim , etc. 
type 
Type of confidence bands. type=0 computes pointwise 95% bands.
type=1 computes basic simultaneous bands with no corrections.
type=2,3,4 are the centered and corrected bands for parametric
regression models listed in Table 3 of Sun, Loader and McCormick (2000).

A list containing the evaluation points, fit, standard deviations and upper
and lower confidence bounds. The class is "scb"
; methods for
printing and ploting are provided.
