Interaction graphs for 2k-p fractional factorial designs
Sometimes in an experiment certain factors whose levels are difficult to change co-exist with factors whose levels can be changed easily. There is thus need to develop interaction graphs which will enable the Scientists and Engineers to develop required linear graphs and to allocate factors among different columns of the orthogonal array on the basis of difficulties involved in changing the levels of the factors. Further these designs satisfy minimum aberration criterion.
