First of all EVOP is much easier to apply than traditional experimental techniques such as response surfaces, factorial designs and even Taguchi methods. It is also more accurate. A second order polynomial is the best approximation to the response surface other methods can make. This assumption limits the accuracy of the final answer. Another problem with conventional methods is the complexity with the number of factors. The table below shows the minimum number of trials required for a response surface design as a function of the number of factors.

Stat-200 is a remarkably comprehensive general statistics package. It incorporates all the descriptive statistics, parametric and non-parametric statistical tests, graphics and data transforms you will need for processing, analyzing and presenting data. Parametric tests and procedures in Stat-200 total 60 and there are 66 non-parametric tests and procedures and 30 different descriptive statistics. ANOVA is comprehensive and includes general N factor analysis. Many unusual procedures are included e.g. survival analysis. All tests have associated information windows which give literature referen
