Calibration Table
A calibration table summarizes bucket counts, average predicted probability, and realized frequency. It is the numeric backbone of calibration curves.
Definition
A calibration table reports calibration statistics by probability buckets. It is the numeric version of a calibration curve.
Typical columns
• bucket range
• count (N in bucket)
• average predicted probability
• realized frequency (average outcome)
Why it matters
Tables make it easy to spot where you are miscalibrated and whether bucket deviations are driven by small sample sizes.
