в которых у – показатель (параметр) процесса;
x0 = +1 ; x1n = x1n + v1 ; x2 n = x2n + v2 ; x3n = x3n + v3 ; x4 n = x4n + v4 ; x5 n = x5n + v5 ;
х1, х2. х3. х4, х5 – 1, 2, 3, 4, 5-й факторы (независимые переменные);
n – изменяемое число показателя степени каждого фактора (n может рав-
няться единице, быть больше или меньше 1);
v1, v2. v3. v4, v5 – коэффициенты ортогонализации, определяемые при двух
уровнях каждого m-го фактора по формуле (2).
        Так как планирование ортогональное, то все коэффициенты регрес-
сии и дисперсии в их определении рассчитываются независимо друг от
друга.
        Применительно к использованию ЭВМ разработан алгоритм матема-
тического моделирования, который сводится к следующему.
1. Начало выполнения программы, ввод количества опытов по плану, ве-
      личин факторов на принятых уровнях и показателей степени в уравне-
      нии регрессии.
2. Расчет коэффициентов ортогонализации.
3. Ввод величин показателей процесса.
4. Расчет коэффициентов регрессии до их анализа.
5. Ввод количества опытов на среднем уровне факторов.
6. Расчет показателей до анализа коэффициентов регрессии.
7. Выявление дисперсии опытов, расчетных величин t – критерия для
      каждого коэффициента регрессии.
8. Ввод табличного t – критерия.
