With regards to the response screening, supposed you have a categorical X (factor) and numerical Y (response), thereby fitting Y by X analysis using Oneway, do the magnitude (size of number) matter in Y? I have e^-20 values in each data, but the values (PValue, LogWorth, RSquare, etc) are being listed as null when I do the response screening. As compared to Python, there are values for PValue and RSquare.
Can somebody confirm to me that this is due to the magnitude in Y being too small? Any comments will be appreciated.Thank you!
The scale should not matter. You can try this easily by performing the analysis in JMP. Now change the scale of your Y by subtracting a constant or choosing the standardize function. Redo the analysis with the modified response. Compare the results.
