I'd like some advice about how to perform integration over an interpolated surface in mathematica.
I had a list of x,y,z points:
x1, y1, z1
x2, y2, z2
xN, yN, zN
that are arranged on a rectangular grid. The x,y values are parameter values, and the z's are log-likelihoods.
I would like to integrate the area under the surface defined by this set of points. I expect that first I need to interpolate the surface, then integrate the result of the interpolation.
Can anyone give me some pointers?
