QUOTE: "From our experience, treating ordinal data as continuous with
constant variance can provide a useful approximation when the number
of response categories is large, but may be inadequate when that
number is less than five." This is on page 2605 of Agresti, Alan &
Chuang-Stein, Christy (1997) "A REVIEW OF TESTS FOR DETECTING A
MONOTONE DOSE-RESPONSE RELATIONSHIP WITH ORDINAL RESPONSE DATA",
