Main Effects Residual Plots in DSD Fit Definitive Screening platform

How are the Main Effects Residual Plots created in the Fit Definitive Screening platform? I've tried to replicate them in Graph Builder but the only plot that comes close is a plot of Predicted Response - Intercept (y-axis) vs Factor levels (x-axis). Basically, normalizing the predicted values around the mean.

Thanks,

Hi @mc1 ,

The way that the residuals are plotted are described as:

The Main Effects Residual Plots plot of the residuals from a DSD main effects model fit to all other factors versus the levels of the plotted factor. A factor with residuals that differ across levels indicates an important main effect.

In laymans terms - if you plotted a main effect model for every term excluding the one you're interested in in the Fit Model platform (i..e main effects of X2-X5, leaving X1 out of the model) and saved the residuals, you then plot the missing term to the residuals (X1 to Residuals of X2-X5).

Hope that makes sense!

Thanks,

Ben

Thank you, Ben! That does make sense.
