20/// RooAddModel is an efficient implementation of a sum of PDFs of the form
21/// \f[
22/// c_1 \cdot \mathrm{PDF}_1 + c_2 \cdot \mathrm{PDF}_2 + ... + c_n \cdot \mathrm{PDF}_n
23/// \f]
24/// or
25/// \f[
26/// c_1 \cdot \mathrm{PDF}_1 + c_2 \cdot \mathrm{PDF}_2 + ... + \left( 1-\sum_{i=1}^{n-1} c_i \right) \cdot \mathrm{PDF}_n
27/// \f]
28/// The first form is for extended likelihood fits, where the
29/// expected number of events is \f$\sum_i c_i \f$. The coefficients \f$c_i \f$
30/// can either be explicitly provided, or, if all components support
31/// extended likelihood fits, they can be calculated from the contribution
32/// of each PDF to the total number of expected events.
33///
34/// In the second form, the sum of the coefficients is enforced to be one,
35/// and the coefficient of the last PDF is calculated from that condition.
36///
37/// RooAddModel relies on each component PDF to be normalized, and will perform
38/// no normalization other than calculating the proper last coefficient \f$c_n \f$, if requested.
39/// An (enforced) condition for this assumption is that each \f$\mathrm{PDF}_i \f$ is independent
40/// of each coefficient \f$i \f$.
