... cause¹

Let suppose to have 3 causes, and let be $N_1$,$N_2$ and $N_3$ the generated number of events, with the luminosity L$_1$,L$_2$ and L$_3$, respectively. The initial probability can be chosen in the following way, normalised to the data, for example:

$$N_{tot} = {\cal L}_{data} \sum_i \frac{N_i}{{\cal L}_i} \;\... ...\cal L}_i} \frac{{\cal L}_{data}}{N_{tot}} = \sum_i P_o(C_i)$$ (5)
