Chi-square for Independence. The command itself is nearly the same as before, but modified to tell Stata that there is a frequency variable by adding [freq=[frequency variable]] with the brackets. Therefore, the command in total reads tab gender genre [freq=freq], chi2 and displays the exact same output as the original command run on the data in long form. Sep 08,  · According to the results of your chi2 test, there is evidence that the compared coefficients do differ (i.e., the null ihypothesis is rejected, as p-value=, is well below the . Using Stata for Categorical Data Analysis. NOTE: These problems make extensive use of Nick Cox’s tab_chi, which is actually a collection of routines, and Adrian Mander’s ipf command. From within Stata, use the commands ssc install tab_chi and ssc install ipf to .
