Calibration curve,直译过来就是校准曲线或校准图。其实,校准曲线就是实际发生率和预测发生率的散点图。实质上,校准图曲线是把Hosmer-Lemeshow拟合优度检验的结果可视化。目前校准曲线常用来评价logistic回归和cox回归模型。 校准曲线案例 image 不同数据集的校准曲线 ...
the calibration curve is frequently utilized to evaluate the performance of logistic regression and Cox regression models.The algorithm for constructing a calibration curve involves several steps. Firstly, the predicted probabilities are grouped (the grouping strategy can be either 'uniform' or...

图3是校准曲线(Calibration curve),AB两图分别预测60个月和120个月结局事件。横纵坐标分别是预测概率和实际概率。本研究考虑到发生事件的时间,运用Cox模型建立列线图(Nomogram)并绘制校准图。论文统计方法部分描述如下: 操作实例 例如:用多个临床指标(年龄、性别和BMI)建立结局指标的预测模型,绘制校准曲线。
