Crosstabulate input and output.
. tab education <whatever>
You will see, I guess, that this is a side-effect
of tied values, given that the same input must map
to the same output.
With the auto data,
. xtile xrep78 = rep78, nq(5)
gives just 3 distinct quantiles, even
though there are 5 distinct (non-missing
values).
