FWIW:  We had a rather interesting thread last week on generation of Bootstrap samples.

@ Margaret:If you have implemented your Hyp test in SPSS or know MATRIX you could use what is in the cited thread and wrap the whole thing on a macro or python extension.

SPSS can be used for many kinds of
      simulation, bootstrapping, monte carlo, etc.   The vocabulary for
      this is not very consistent across disciplines.
     
      There are many different kinds of functions for generating random
      values "*.rv.something(arg1, arg2...).
      There are many cumulative and inverse distribution functions.
      it also have a vast array of hypothesis tests that you could
      contrast with your test.
     
     
      What is the conceptual type of hypothesis you are testing? 
      What is the conventional way to test this kind of hypothesis  that
      you want to show improvement over?
      Are there specific assumptions that you want to relax?
     
      What is the part of the test that you want to show is an
      improvement?
     
     
      Have you implemented your test in SPSS syntax?

        Hello
         
        I would be grateful to learn from any list users who have
          used SPSS successfully for bootstrap sampling to assess
          robustness to Type I errors of a proposed new hypothesis test.
         
        Many thanks in advance
         
        Best wishes
