FRACTION: A computer program for fractional factorial design [PDF]
Factorial designs are used efficiently and effectively to carry out experiments involving multiple independent variables needed to explain complex human behavior. These designs are not feasible, however, when a study requires a large and, in some cases, prohibitive number of measurements on the same subjects (within-subjects designs) or on groups of ...

The optimization of b-glucan production by Ophiocordyceps dipterigena BCC 2073 was carried out. For the three-step optimization performed in 250-mL Erlenmeyer flasks, at the first step, the maximum b-glucan production of 16.48±0.60 g/L was obtained using

Resolution Iv Fractional Factorial Designs
Summary Fractional factorial designs of resolution IV permit estimation of all the main effects with no aliasing by two-factor interactions. This paper produces a lower bound for the number of observations required for a general fractional factorial design to be of resolution IV. This lower bound agrees with a lower bound obtained by Rao
