Hello,
I have been trying to take the derivative of a quadratic B-spline
obtained by using the COBS library. What I would like to do is
similar to what one can do by using
fit-smooth.spline(cdf)
xx-seq(-10,10,.1)
predict(fit, xx, deriv = 1)
The goal is to fit the spline to data that is

Would the unique quadratic defined by the three points be the same
curve as the curve predicted by a quadratic B-spline (fit to all of
the data) through those same three points?
