Predict interval prediction

WebA confidence interval of the prediction is a range that is likely to contain the mean response given specified settings of the predictors in your model. Just like the regular confidence intervals, the confidence interval of the prediction presents a range for the mean rather than the distribution of individual data points. WebSecond, predictive performance was compared among the six prediction rules and criteria for CAP-DRPs including HCAP, 4 Shorr, 15 Aliberti, 5 Brito and Niederman, 20 Schreiber, 22 Prina, 21 and Shindo’s CAP-DRP rule . 11 When comparing original cutoff scores or criteria that are shown in Figure 1, sensitivity of the CAP-DRP rule (0.45) was lower than those of …
