“…318–319) with two replications at each of the five percentages of sucross and , our program gives (taking less than 2 seconds) which agrees with the entry 3.304 of Spurrier , Table , with , and ). For the numerical example given in Trout & Chow (, p. 622) with and , our Matlab program gives (taking less than 3 seconds) while Trout and Chow gave using their integration method and from their interpolation. As pointed out in the Introduction, the methods of Spurrier () and Trout & Chow () involve a three‐dimensional integral and so are slower computationally than our method which involves a two‐dimensional integral.…”
