DOE significance level test (beginner problems ...)Hello everybody,
I am new and therefore not familiar with the program / forum, I would be very happy about help.
I would like my test results: tensile strength, elongation at break, tension, Shore hardness near / far, as well as the density for significance to my test parameters: check the proportion of microspheres, tool temperature and dosing path, but unfortunately I do not get any reasonable results.
Maybe the wrong approach but my only one:
(when trying to follow the help (DOE GUIDE p.51) I get the message No valid factor table when loading my factors)
Many thanks at this point for time and effort.
Re: DOE Signifikanzniveau test (Anfänger Probleme...)Hello,
That part of the guide deals with designing the experiment, not analyzing. Loading factors has to do with importing pre-specified factors and factor levels, which is a convenient way to not have to re-input the factors over and over when you are iterating through several design options.
You need to use Fit Model of another analysis platform from the Analyze menu to perform the analysis on your results. In the dialog for Fit Model you will specify the model terms you want to fit to your DOE data. See the Fitting Linear Models guide in the Help menu for further direction.
Re: DOE Signifikanzniveau test (Anfänger Probleme...)I think there are three rules for successful data analysis:
1. Plot the Data.
2. PLOT THE DATA.
3. PLOT THE DATA.
As a precursor to using the Fit Model platform as recommended by @cwillden , I recommend using Graph Builder or the Fit Y by X platform and create the following plots asking these question:
1. Do the results make sense from a process knowledge point of view?
2. Are there outliers or suspicious looking observations that will make subsequent analysis problematic?
Use Graph Builder or the Fit Y by X platform...
1. Each factor vs. response (a scatter plot).
2. The response(s) histograms.
3. The response(s) in experimental execution order.
