![]() Note Due to the specific nature of this case study, a number of features that could be helpful to you for RSM will not be implemented in this tutorial. Many of these features are used in the earlier tutorials. If you have not completed all these tutorials, consider doing so before starting this one. We will presume that you are knowledgeable of the statistical aspects of RSM. For a good primer on the subject, see RSM Simplified (Anderson and Whitcomb, Productivity, Inc., New York, 2005). You will find overviews on RSM and how it’s done via Design-Expert in the on-line Help system. They should have left it as 1-4 maps are no shoot for all levels and make is as above level 10 they cannot pick up shineys or chest thus giving new players a chance to get thier ships a bit stronger, you have ships that are staying below level 15 to be able to go into the sun raid map sinking out little players who do not have the ability to fight back. Come on BP how many new players have tried to play and given up due to this? Glitter bot seafight cheats. They should have left it as 1-4 maps are no shoot for all levels and make is as above level 10 they cannot pick up shineys or chest thus giving new players a chance to get thier ships a bit stronger, you have ships that are staying below level 15 to be able to go into the sun raid map sinking out little players who do not have the ability to fight back. Get a grip on things because we keep losing old players through botters and new players through no where for them to build up.

This was a very useful exercise as it supported the surfacing of meanings that were dissimilar and created space for discrepancies to be seen, significant for. To gain a working knowledge of RSM, we recommend you attend our Response Surface Methods for Process Optimization workshop. Call Stat-Ease or visit our website for a schedule at www.statease.com. The case study in this tutorial involves production of a chemical. The two most important responses, designated by the letter “y”, are. • y1 - Conversion (% of reactants converted to product) • y2 - Activity. The experimenter chose three process factors to study. Their names and levels are shown in the following table. Factor Units Low Level (-1) High Level (+1) A - Time minutes 40 50 B - Temperature degrees C 80 90 C - Catalyst percent 2 3 Factors for response surface study You will study the chemical process using a standard RSM design called a central composite design (CCD). It’s well suited for fitting a quadratic surface, which usually works well for process optimization. Default CCD option for alpha set so design is rotatable Many options are statistical in nature, but one that produces less extreme factor ranges is the “Practical” value for alpha. This is computed by taking the fourth root of the number of factors (in this case 3¼ or 1.31607). See RSM Simplified Chapter 8 “Everything You Should Know About CCDs (but dare not ask!)” for details on this practical versus other levels suggested for alpha in CCDs – the most popular of which may be the “Face Centered” (alpha equals one). Press OK to accept the rotatable value. (Note: you won’t get the “center points in each axial block” option until you change to 2 blocks in this design, as below). Using the information provided in the table on page 1 of this tutorial (or on the screen capture below), type in the details for factor Name (A, B, C), Units, and Low and High levels. ![]() Enter the Response Data – Create Simple Scatter Plots Assume that the experiment is now completed. At this stage, the responses must be entered into Design-Expert. We see no benefit to making you type all the numbers, particularly with the potential confusion due to differences in randomized run orders. Therefore, use the Help, Tutorial Data menu and select Chemical Conversion from the list. Let’s examine the data! Click on the Design node on the left to view the design spreadsheet.
