The relative error in the joint entropy calculation between the joint entropy calculated through truncation and the joint entropy calculated by our approximation. It is clear that when both \(\lambda _{12}\) and \(\lambda _{11} \lambda _{22}\) are small, the relative error is small. Thus we expect this approximation to work well when all of the estimated rates are small. In practice we find that when scaling the rates to be in [0, 1] we get good results, regardless of how high the true rates were
