2. The Nonuniform Poisson Counting Process N(t) is defined for 120 as follows (a) N(0)=0 (b) N(t) has independent increments (c) For all 2>t1, [a(v)dv P[N(t2 ) - N(t, ] = exp -[a(v)dv , n>0 n! A(t) is called the intensity function. Compare this with a Uniform Poisson Counting Process and find a. Its mean function mean function /v(t) b. Its correlation function RNM(t1,12)
