Nonlinear measurements might be expected to confound, but do they belong in a statistical model hierarchy?
– By Rick Danielson Jr –
A statistician and physicist were discussing an experiment over a pot of tea, when this hypothetical exchange occurred: “I know we are working in the right units, but do you think that some of our measurements are nonlinear?” Puzzled, the physicist took a sip before responding, “Are you saying that individual measurements could be nonlinear? Is that a thing?”
