Test of Applicable Condition for Polytomous Logistic Regression on Ordinal Response

Objective To seek scientific and reasonable mothod of test applicable condition for polytomous logistic regression on ordinal response.Methods the theory of Chi square distribution,the SAS system and sampling survey were used.Results Chi square test of applicable condition for polytomous logistic regression on ordinal response was designed,the formulas of probability of response variable at different levels and theoretical value and degree of freedom for Chi square test were deduced,the test was applied successfully in the clinical examination for national licensing of doctors.Conclusion Polytomous logistic regression for ordinal response was perfected,it has greater significance of theory and practice.
