Ultimately I hope to determine the probability of a
> a given data set being exponentially distributed,

In this case, you could use a non quadratic fit function, with a pseudo
norm1 cost ( for instance sqrt(eps + (y-f(x))²) with a small eps so that the
cost is derivable and a gradient descent should do the trick).
