Line Plot from Scientific Research

Predictions on the validation and testing datasets, in increasing order, were binned together into ten groups of 221 predictions. Event rates (observed risk) were calculated along with confidence intervals and plotted against the mean predicted probability per group to create the dot and whisker plot. Smooth lines were plotted using the individual predicted probabilities and yes and no outcomes, with Linear (red) and Loess (blue) methods. Cox calibration intercept and slope, Brier score, and Spiegelhalter Z scores were calculated.
