-help tabulate twoway- describes the result from the -chi2- option as:
"chi2 calculates and displays Pearson's chi-squared for the hypothesis
that the rows and columns in a two-way table are independent." 

This is a very short description, but does contain all the necessary
information. If you had forgotten the details of a Pearson's
chi-squared test, the manual contains a more detailed description, or
you can look that up in your favourite intro stats book or google it.
