Nonparametric regression


Super Moderator
Hi guys, can someone recommend a good source to learn about kernel regression or spline smoothing and perhaps how to compare two plots to each other?

I would suggest you look at:

Green, P.J. & Silverman, B.W. (1994). Nonparametric Regression and Generalized Linear Models: A Roughness Penalty Approach. Monographs on Statistics and Applied Probability, 58. Chapman & Hall: London.

In terms of explanations, you would do well to go past these.
They use water quality as their example, but they explain the concepts very well.
