Dear All,

I am Maheswaran Kesavan doing masters in University college London.

I am doing an Non parametric series regression using B spline basis.
Now I want to know 1) Where the knot lies in my data.
2) How to incorporate a knot at a specific point of my choice.
3) How to plot the curve for Non parametric series regression.
4) What is the minimum number of data points we can use in Non parametric regression models (mine is 100)

Thank you in advance.
