Active Screening Experiment-Method of Random Balance

Active Screening Experiment-Method of Random Balance 

The application of screening experiments is obligatory when operating with a relatively large number of factors (k 7), because in the first phase, it facilitates the inclusion of all those factors that do not affect the response greatly. Thus, they also considerably simplify the research of the factor space-domain and the modeling of the response surface. An active selective method, which may be applied in solving this problem is the analysis of variance. 

Analysis of variance, as has been said in Sect. 1.5, is based on the fact that the significant effects of certain factors depends on their contribution to the response variance. The analysis of variance is in practice less frequently used in cases of a
