<Felix A. Wichmann> studied <psychophysics> and estimation of <psychometric functions>. Work on fitting, sampling and model checking connects sensory thresholds to the uncertainty of the data used to estimate them. Comparing plausible <FITs> and their sampling <behavior> is important before attributing a small threshold difference to a change in <perception>. <The psychometric function: I.
