- Applying Of Logistic Regression In Medical

Use survival time

Proposed by Cox(1972)

Use the Logistic Model Method and Cox Model Method to compare the result ,which can quickly detect the patient has a shoulder joint shift or death situation.

- Applying Of Cox Model In Medical

- Calculate and Simulation

Collection and Simulation of patient information

- Establish

Logistic Model

- CUSUM control chart

Notation and Assumptions

- Calculate ARL

- Comparative analysis

- Conclusion

- Monitoring probability of Yt

- Binary data is transformed into probability

- Establish a Logistic Regression Model
- Find the significant factor

- Calculate the weight value

- Steiner et al.(2000)

- Draw CUSUM control chart

- Monitoring probability of Yt

- Yt of time conditions convert the probability of occurrence

- Establish a Cox Regression Model
- Find the significant factor

- Calculate the weight value

- Biswas ed.(2008)

- Draw CUSUM control chart

- Simulate number of samples N

- calculation the patient t the surgery the probability of failure

- is true

- To draw CUSUM control chart ， and monitoring control chart
