Don't worry if this looks crazy - the SciPy package in Python will do all the heavy lifting for us. As with the single-variable distributions, we're going to use this to find how likely a certain observation is. In other words, if we put <math>k</math> points of our power trace into <math>\mathbf{x}</math> and we find that <math>f(\mathbf{x})</math> is very high, then we've probably found a good guess.
