The confident integer okay = X0 is the dimensions of the inhabitants at time t = zero. therefore, via definition, the predicted price of Xt is E(Xt ) = ∑ jpj (t) . j≥k we are going to now use the notations brought within the prior part, zero < w = e−bt ≤ 1, 0≤z =1−w <1 , and compute the worth of the sequence defining E(Xt ). we've got 132 Jens Lorenz ∑ E(Xt ) = jaj e−jbt (ebt − 1)j−k j≥k ∑ = j≥k ∑ = jaj wj (1 w )j−k −1 jaj wk (1 − w)j−k j≥k ∑ = jaj (1 − z)k z j−k j≥k We declare that the worth of the sequence equals kebt , i.
