Bo MacInnis-• Rao-Scott corrected chi square = (R-1)(C-1) x (corrected F) whereR= no. of Rows C = no. of Columns (Stata 11 Manual, page 130)• In your example with R=2, C=2, the statistics are identical. • SAS reports only the F approximation p-value, just as Stata does.

The two-way svy:tab provides the Pearson statistics(uncorrected for design-effect as well a design effect adjustedbased on Rao-Scott (1984). However, the design-based Pearson isconverted into a F-stat. In my project, I'd need the chi(2) versionof the Rao-Scott statistic (like what is provided in SAS, but I donot use SAS).Here is the output from a two-way (2x2) svy:tab: Pearson: Uncorrected chi2(1) = 2.3737 Design-based F(1, 2803) = 1.4764 P = 0.2244 Thank you very much for your help!
