Hello Community,
I have a question concerning the models found for Mixture DoE when the default L PseudoComponent Coding is activated (default conditions).
When this is activated, my main effects have strange forms like in the picture below:

I prefer when they have a cleaner view, just Oil, water and vinegar (not in the form of ratio). Apart from the visual aesthetics preferences, there is something that confuses me even more. When I export ththe equation for this case and I simplify it, it looks like:

The number in the green circle seems to me like an intercept and in mixture doe, the model normally does not have intercept.
My first question would be: If I want a more visually aesthetic model, I know I can just uncheck the L PseudoComponent coding. However, what is the danger of doing so?
My second question is: Why I’m seeing an intercept in my model in this mixture case?
Thank you,
Julian
