ABSTRACT
L = K[1 - P(a) Y' e-"" A"{Q X;!] -I [P(d + 1W', (13.2.28) where K is an ordering constant and other symbols are as previously defined. We take logarithms of (13.2.28), differentiate with respect to A, and equate to zero to obtain the estimating equation
Subsequent simplification yields
X = A [ 1 + ~ ( {~ P(~ ] - ~ ( P(~(~ 1) ) l (13.2.30) and the estimate ~ follows as the solution of this equation.
