I'm desperately uninformed about the methods you have been discussing, but for
a non-parametric solution, how about splines?
Carl DeBoor (1978) outlines a method of area preserving quadratic splines to
fit histograms. All you need to know is the value each bar represents and its
interval. I am
I think I have a spline problem, and I would like to implement the
solution in S. There are a lot of spline algorithms and I am looking for
some direction on what is most appropriate. I need a spline that can be
made to extrapolate certain data points as described below. Of course it
needs to
