what is optimal calibration for a cox model how accurate is a cox model prediction how do you measure accuracy in a model why is the cox model used for prediction can predict risk of incident disease be tuned why is model calibration important when is the threshold of a cox model how do we tune the models for predictive performance of a range? why are models tuned for specific probability why calibration is important on a model can a predefined probability range be tuned for predicting a disease which model is best for prediction? when the threshold for accuracy is greater than the threshold for accuracy, the model is tuned to what models should accuracy be why is model calibration essential why tuning a model for predictive performance in a narrow probability range is important how to optimize predictive accuracy how accurate is a cox model predictive what is the accuracy of the prediction accuracy of the cox model when to use a predictive model
