Unfortunately these areas do not coincide. We can, graphically, see the optimal areas to maximize Yield and to minimize Cost. Graphical Representation of the Response Surface ModelWe can now see graphically the impact of the 3 factors in Yield with Contour Plots: you will need to purchase multiple different softwares such as: Minitab for Statistical Analysis. We recommend that you select the desktop, then click on the Desktop. All the tools included at one attractive price point. Some competitor software products to StatPlus include Minitab Statistical Software, Statgraphics, and Alteryx. Software pricing starts at 9.99/month/user. You will be prompted to choose the location to save the files. Talk to Minitab India to know the Minitab Price in India, Minitab License Costs, Minitab Renewal Costs, & more. StatPlus is data analysis software, and includes features such as data visualization and regression analysis. Right-click the Installer collection and select All. This is the formula to estimate Yield as a function of Temperature, Time and pH. Download the Minitab 18.1.0 Installer store from the CU software Minitab page. The resulting reduced model for Yield is then: Therefore we will remove both from the model: Reduced ModelNow we confirm that both Temperature^2 and Temperature*Time do not,significantly, affect Yield or Cost. Before we remove these from the model we must make sure they do not significantly affect the other output variable (Cost) we try to optimize:

Only the Temperature*Time interaction and Temperature^2 are not significant. R-sq(adj) value of 96,85% confirms the validity of this model.

Run the Response Surface ExperimentsTo run the experiments we copy columns C5-C7 to our simulator:Īnd back the results of the experiments (Yield and Cost) to the new Minitab worksheet:Īnalysis of the Response Surface ResultsWe now perform the analysis of the Response Surface Design: The resulting response surface design is:
