| Abstract: | Objective To explore the ROC analysis methods for repeated ordinal categorical data in diagnostic test. Methods ROC models are given based on ordinal regression models, and cumulative logistic models are used as the link function. The parameters can be estimated by using generalized estimating equations(GEE) method. Results ROC curve equation, areas under the ROC curve and standard error are estimated by the cumulative logistic models. Conclusion The methods in this paper can analyze and process effectively the repeated measures data in the image diagnostic test. |
