Calculating area between two spline fits (bivariate)
I have used fit spline of the bivariate platform to parameterize fluorometric spectral curves and saved the prediction formula for my samples as well as blanks. I want to estimate the area under the peak, or more precisely, the area between the curves of the sample and the blank within a specified wavelength interval.
I could certainly do this in matlab with some effort, but it would be neat keep t...
