Fisher exact test possible with CSTABULATE command?

Shirin Nuesslein
Hello, 

I am working with the CSTABULATE command for my complex sample. Is it possible to run the CSTBULATE /TEST subcommand in a way that gives me the Fisher's exact test of independence? It appears that the default option is a Pearson's chi-square test, and I don't see a way to modify this.

Is there a work around anyone is aware of?

Any pointers appreciated! 
Thank-you!

Fisher's Exact Test is for 2x2 tables.  That seems inconsistent with
your mention of "complex sample."

There are two or three "exact tests" based on permutations and
different criteria, but all the usual ones are employed on two-way
tables. That also seems inconsistent with complex samples.

The documentation for CSTABULATE /TEST does lists the following options:

HOMOGENEITY. Test of homogeneous proportions. Available for one-way
frequency tables only.

INDEPENDENCE. Test of independence. Available for two-way crosstabulations
only.

ODDSRATIO. Odds ratio. Available for two-by-two crosstabulations only.

RELRISK. Relative risk. Available for two-by-two crosstabulations only.

RISKDIFF. Risk difference. Available for two-by-two crosstabulations only.

And the Algorithms Doc gives all the details about these testsif you really want to know.
