When considering the uncertainty on the overall integral, both the errors on the ''u'' parameters  

and those from the finite MC set of events will contribute. A single detected event (i) can be viewed as one sample in a process of independent events, having therefore a count uncertainty of

and those from the finite MC statistics will contribute.   The part of the error on the intensity coming from the finite MC statistics is computed using the usual rules for error propagation.

σ_i=1. An integral over such events is then a weighted sum of such samples,

having resulting in a contribution to the variance:
