STAVEX is a user-friendly PC-based software system enabling experimenters in research and development to apply statistical design and evaluation of experiments in their routine work independently of a statistician. STAVEX studies the relationship of specified factors and responses. The ultimate goal is to find the optimal settings of all factors actually influencing the responses.

STAVEX allows for process factors, like temperature or concentration, as well as for mixture factors which have to fulfill a summing-up condition typical for mixtures or formulations. STAVEX also supports the combination of responses in the form of a cost function assigning weights to the responses or a desirability function combining individual specification intervals. This way trade-offs between the responses can be studied.

STAVEX supports sequential planning, it integrates statistical experimental design, statistical evaluation of results, and guidance to follow-up designs, i. e. the whole process of experimentation. This way, STAVEX typically runs through 3 stages of statistical experimental design: screening using linear models for factor reduction, modelling for further factor reduction using linear models with interactions, and optimisation for determining the optimal levels of the remaining factors.
