Fractional Factorial DesignsSequential DesignsIt is sometimes necessary to perform two-level factorial designs in blocks of size two. We investigate what combinations of designs in different pairing arrangements permit estimation of all main effects and two-factor interactions. The confounding patterns of ...
"Best" combination designs were given which provided the most pure (within block) estimates of main effects and two-factor interactions from choices that combined various confounding patterns. Extensions were also given for2k-pfractional factorial designs with the same number of runs (that is, when...

However, in the factorial design, the between-group variance estimate is itself partitioned into several parts: variation because of the first factor; variation because of the second factor; and variation because of the joint effects of the two factors, called the interaction. This chapter ...

Two-level factorial designs for main effects and selected two-factor interactions From a practical viewpoint the first decision to be made in the construction of a design of a two-level factorial experiment is the choice of the parameters of interest. It is convenient to represent such a choice...

A two level factorial design was adopted to assess the effect of the above mentioned factors on the microbial inhibition by PLJ. The results show that the most contributing factor of 1.55 % was reaction temperature, meanwhile the highest contribution factor for interaction effect was between ...
