| Abstract: | In this article,we propose the method of statistical test for the problem that there exist differences between categories of the ordinal variables on the basis of defining the cumulative logistic model,and then introduce the instrument dummy variable into the model to improve it.This method is proved to be effective when applied in practice. |

| Keywords: | cumulative logistic model ordered categorical variables instrument dummy variable |
