When analyzing the results from a DoE, I have noticed that the values from the model report for a given factor do not make intuitive sense with the trends in the prediction profiler. For example, some factors have a value of "0" in the Model Report > Total Sensitivity, but then the prediction profiler shows a trend (bell curve, for example) implying that there is a clear impact on the response value as the factor is changed. Why would the line shape in the prediction profiler not be a flat line for a factor that has a "0" total sensitivity?
Please let me know where the gap in my understanding is. Thank you.
