Reliability Diagram
A reliability diagram is a graph where the conditional distribution of the observations , given the forecast probability, is plotted against the forecast probability. The distributions for perfectly reliable forecasts are plotted along the 45-degree diagonal. A guide is shown below.
The more tightly data points are packed along the central 45-degree diagonal line, the better the model . An example is shown below.
You can see that in this case, fair-or-better forecast reliability for correct disease status prediction was observed for most points except for x =0.25 and x =0.91.
