Test Equality of Curves with Homoscedastic or Heteroscedastic Errors.
For each value $at$ in the defining interval, find a bandwidth $h$ so that alpha*100 percent of data points specified in $xseq$ should be within the $(x-h, x+h)$ window. This is a utility function.
alpha2h(alpha, at, xseq)
Smoothing parameter that for each point in the domain, use a windown width that should have alpha*100 percent of data points falling in the window.
a point in the x domain.
Sequence of the data points.
A numeric value h that will be used as bandwidth in the next curve fitting process.
