The values J1(j) still defme the distribution of notifications over development periods. 16) which is independent of i . This suggests taking the ratios N(iJ)IN(i,O) whose expectation is E [N(i,j)IN(i,O)] = E N(i,j) x E[lIN(i,O)], if the two quantities are stochastically independent. 17) Now suppose that N(i,O) is = E[E N(i,O) + = [liE N(i,O)] x E[1 + e/E N(i,OW 1 = [liE N(i,O)] x [1 + V(e)/[E N(i,O)f ] to second order = [liE N(i,O)] x [1 + liE N(i,O)]. 18), E [N(i,j)/N(i,O)] = E N(iJ)/E N(i,O) x [1 + liE N(i,O)].
