If your p-value (Prob > chi2) is less than your chosen level of significance than you can conclude that you rejected your null hypothesis. You did not say which level of significance you have chosen, so I'll assume you use the customary but arbitrary 5% level. 0.0000 is less than .05, so you reject the null hypothesis. The null hypothesis is that the cuts are equal. So you reject the hypothesis that the cuts are equal. -- Maarten --------------------------------- Maarten L.
