Hey I've been attempting to draw the non-parametric part of a regression on a scatter plot, with confidence intervals if possible. Even if I tried, I failed, reason why I'm asking here
library(np) library(foreign) wage1 <- read.dta(file="PATH HERE\\wage1.dta") reg.np <- npplreg(lwage ~ female + married + educ + tenure | exper, data = wage1) plot(reg.np) plot(wage1$exper, wage1$lwage, xlab = "age", ylab = "log(wage)") lines(wage1$exper, fitted(reg.np), lty = 1, col = "blue") This was one of the many attempts I tried. I'd really appreciate if someone could help. wage1 Database: http://www.sendspace.com/file/txksv3 Thanks!
