  In what context?

  The only R-context answers I can think of are "Peter Dalgaard"
(an R-core member) or "positive definite" (see ?pdClasses in
the nlme package).

   You're probably not looking for <http://en.wikipedia.org/wiki/PD>

  good luck -- if you give more context you might get a more
useful answer.
