We propose a general and unified approach to the selection of regular fractional factorial designs, which can be applied to experiments that are unblocked, blocked or have a split-plot structure. Our ...

Fractional factorial designs are widely used in various scientific investigations and industrial applications. Level permutation of factors could alter their geometrical structures and statistical ...

Full factorial DOE, or Design of Experiments, is a method of designed experimentation. Using this method you manipulate the ...

Experimentation is a vital part of the scientific method. Most problems in science require observation of the system at work and experimentation to elucidate information about how the system works. In ...

In the present investigation, the fixed-dose combination (FDC) tablet of Atorvastatin calcium and Ezetimibe was prepared by a quality-by-design approach using two-level factorial design. In the ...

Factorial designs involving two levels are the most popular experimental designs. For two-level designs, it is assumed that the response is close to linear over the range of the factor levels. To ...

The FACTEX procedure constructs a fractional design for q-level factors using the Galois field (or finite field) of size q. This is a system with q elements and two operations + and ×, which satisfy ...
