Description
Return positive fraction under a missing-data denominator policy.
Behavioral-study coding depends on observation intervals, missing samples, event records and assignment rules. Partial-, whole- and momentary-sampling summaries answer different questions; local agreement or coverage does not establish actual behavior, a diagnosis or an effective intervention.
Return positive fraction under a missing-data denominator policy.
When to use this tool
Use Behavior Observation Missingness Denominator when checking the stated behavioral-research observation, assignment, coverage or coding convention.
How to use the tool and how it works
- Enter positive, negative, missing, excludeMissing. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominator, positiveFraction, missingFraction. Use the output convention below.
Return positive fraction under a missing-data denominator policy. Require nonnegative whole counts and positive selected denominator; denominator excludes missing only under policy, while missingFraction always uses all counts.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| positive | Positive | Required. Safe integer; minimum 0. |
| negative | Negative | Required. Safe integer; minimum 0. |
| missing | Missing | Required. Safe integer; minimum 0. |
| excludeMissing | Exclude Missing | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominator | Denominator | Required. Safe integer. |
| positiveFraction | Positive Fraction | Required. Finite number. |
| missingFraction | Missing Fraction | Required. Finite number. |

}Limitations and assumptions
- Positive and missing fractions may use different bases; no missing outcome is imputed and no sampling or clinical inference is made.
- 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 verified observations and the study’s complete sampling/coding protocol, with appropriate statistical and professional interpretation for health or intervention decisions.
