We become aware of a common expression only after it has already gained currency, so it is difficult to identify the original eponymist
. In this case, however, we know exactly when the expression "Tobit model" was introduced, and who the eponymist
was: "An alternative one-step procedure is the extension of probit analysis developed by Tobin (1958) that we designate the Tobit model" (Goldberger 1964, 253).
This work was first published in 1991 by the Royal Society of Medicine in its series Eponymists
in Medicine and this new impression appearing 18 years later is a fitting tribute to this outstanding biography of a remarkable, but forgotten, man.
