x |
a vector of values for the predictor variable x. |
y |
a vector of values for the response variable y. |
nsigma |
a multiplier for the standard deviation function. |
col, bg, pch, cex |
numeric or character codes for the color(s), point type and size of points; see also |

further argument passed to the function |
The function loess.sd
computes the loess smooth for the mean function and the mean plus and minus k
times the standard deviation function.
The function panel.loess
can be used to add to a scatterplot matrix panel a smoothing of mean function using loess with variability bands at plus and minus nsigmas
times the standard deviation.
