|scb||Simultaneous Confidence Bands||scb|
scb(x, ..., mg, flim, type)
scb is implemented as a front-end 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.
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.
locfit, print.scb, plot.scb.
