Abstract

Well-behaved Thurstonian-type models are incompatible with psychometric functions that sat- isfy Regular Minimality and have nonconstant minima. We show, however, that even very simple Thurstonian-type models can provide tolerable approximation to empirical estimates of psycho- metric functions in which Regular Minimality holds within experimental error and the minima are nonconstant.
