Greetings, I used the Locift package for smoothing xy-data using R and the standalone locfit-program (both from <http://cm.bell-labs.com/cm/ms/departments/sia/project/locfit/>).
One can add datapoints and 95%-confidence bands to the fit by the following command [R]: > fit <- locfit(y~x, data=name, alpha=0.25) > plot(fit, get.data=TRUE, band="global") This plots 95% confidence band using a using a global variance estimate and original data points to the fit. Does anybody how to geht the xy-Values of the confidence band out of the program to a table? Getting the data of the fit at any point x is no problem. It seems that the function calculates the standard error at each ponit, but is there a way to get the values of the conf. intervals at a point x directly?
