WebPROC FREQ assigns a name to each table that it creates. You can use these names to refer to tables when you use the Output Delivery System (ODS) to select tables and create output data sets. For more information about ODS, see Chapter 20: Using the Output Delivery System. Table 41.22 lists the ODS table names together with their descriptions ... WebDo you see the exact 95% confidence intervals for the two diagnostic tests as (0.73, 0.89) and (0.63, 0.76), respectively? The SAS program also indicates that the p-value = 0.0262 from Fisher's exact test for testing \(H_0 \colon p_1 = p_2\) . Thus, diagnostic test #1 has a significantly better sensitivity than diagnostic test #2.

I recommend you use Fisher's exact test when the total sample size is less than 1000, and use the chi-square or G ... WebSAS gives you the 2x2 table so that you can check on its formulation of risk. SAS will do an overall chi square test. Beware, the chi square is an approximate test that is not always valid.
