The Panjer recursion is an algorithm to compute the probability distribution approximation of a compound random variable $${\displaystyle S=\sum _{i=1}^{N}X_{i}\,}$$ where both $${\displaystyle N\,}$$ and $${\displaystyle X_{i}\,}$$ are random variables and of special types. In more general cases the … See more We are interested in the compound random variable $${\displaystyle S=\sum _{i=1}^{N}X_{i}\,}$$ where $${\displaystyle N\,}$$ and $${\displaystyle X_{i}\,}$$ fulfill the following preconditions. Claim size distribution See more The following example shows the approximated density of $${\displaystyle \scriptstyle S\,=\,\sum _{i=1}^{N}X_{i}}$$ where $${\displaystyle \scriptstyle N\,\sim \,{\text{NegBin}}(3.5,0.3)\,}$$ and As observed, an issue may arise at the initialization of the … See more The algorithm now gives a recursion to compute the $${\displaystyle g_{k}=P[S=hk]\,}$$. The starting value is $${\displaystyle g_{0}=W_{N}(f_{0})\,}$$ with the special cases See more • Panjer recursion and the distributions it can be used with See more WebPanjer and Wang [21] show that, for non-degenerate severity distributions, the numerical stability of Panjer’s recursion with claim number distribution in the Panjer(a,b,k) …
