1.6.2 Calibration plot 校准图是对实际发生频数与模型预测发生频数相关性图,常用三种形式:①散点图,如图1-19所示;②柱状图,如图1-20所示;③线图或折线图,如图1-21所示。 对于Logistic回归的诊断模型,训练集和验证集的H-L和校准曲线都需要做;对于COX回归的预后模型,训练集和验证集的校准曲线都要做,如图1-22和...

(1)for any Operative system in R programming. Therefore, the Data input is the same as Calib 8.02 input based on Intcal package which created by Maarten Blaauw(2). Also, it is able to plot and create output data in a file in the format .csv. Bellow, I attached this script and ...

Then, the sensor faults were diagnosed using the Q-contribution plot showing the contribution of the individual sensors to the Q-statistic to identify a faulty sensor. Finally, the faulty measurements could be reconstructed by the estimates of the given errors (or correction constants) in ...
