По результатам таблицы ANOVA видно, что параметр TAU является очень важным, так как его F-статистика намного превышает Fкр (668.815 > 4.26).

2.6 Отсеивающий эксперимент

Проведем отсеивающий эксперимент для определения наиболее важных факторов, влияющих на моделируемую систему. И выберем варьируемые величины исходя из результата опыта [1].
