Quantitive Histogram Comparison

[RobbieM.]

I have two histograms that I would like to compare quantitatively. The values of the first histogram have respective relative errors for each bin. The second histogram has no statistical uncertainty.

I could compute probabilities for each bin that the exact values would fall into a given uncertainty range about the corresponding value in the other distribution... but I'm wondering if there are more sophisticated alternatives that I could apply.

If it is relevant, the width of the sample space is the same for all the bins and values in the distributions span several orders of magnitude.

Just in case that numerous people haven't already suggested this to you, try Pearsons Chi-square test.
