“…Then N_-&V E(N(N-1)) = 2 N(N-1)(3V) c. (3)(4)(5)(6)(7)(8)(9)(10) N=2 Ni = (EV) 2 1 (El/') 4e-EV . Since the average of the square of a. statistic is the maximum likelihood estimator of the variance ( 21,), <( f K.)1>= v (K), (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) .and since Ni is a poisson statistic Since the diffusion area (L2) is defined to be (D/Ea), I<* can be expressed as a function of Eir. An expression for w2 can be developed using the definition of w2 in the limit of thin spherical shells (See equation ) and the expression for w(r), ..…”
