Description
Check a probability score against independently open or closed band edges.
Classification scores rank labels or locate a prediction relative to a chosen decision boundary. Raw scores and logits need not be calibrated probabilities; exact ties, score direction and inclusion of boundary values are separate policy choices that can change the reported decision.
Check a probability score against independently open or closed band edges.
When to use this tool
Use Classifier Threshold Open Closed Band when checking the stated score comparison, tie or decision-band policy.
How to use the tool and how it works
- Enter score, lower, upper, includeLower, includeUpper. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inside. Inspect inside before interpreting the associated values.
Check a probability score against independently open or closed band edges. Require bounded score/lower/upper and ordered bounds; inside includes an exact edge only under its corresponding flag.1

| score | Score | Required. Finite number; minimum 0; maximum 1. |
| lower | Lower | Required. Finite number; minimum 0; maximum 1. |
| upper | Upper | Required. Finite number; minimum 0; maximum 1. |
| includeLower | Include Lower | Required. Boolean. |
| includeUpper | Include Upper | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| inside | Inside | Required. Boolean. |

}Limitations and assumptions
- This tests a supplied decision band, not confidence intervals, calibration or an optimized rejection policy.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a complete evaluation dataset and an explicit decision policy to assess performance; fit and validate calibration separately when a probability interpretation is required.
