How could you graph cubic and squared terms in the video?
Thank you

I use R for plotting. In particular, I used the splines package as well as the matplot() function to plot those functions. For example:
library(splines)
nspline

@@lesliemyint1865 Thank you, Leslie. I also tried on Stata by using Local Kernel regression. Will try with R as per your instruction soon.
