Description
Correct a research motion value for zero and axis direction.
Research effect estimates depend on outcome definitions, unit conversions, orientation and statistical assumptions. A written rounding envelope describes reporting precision; an effect-size contribution or supplied interval is different from a fitted analysis, a confidence statement or evidence of clinical benefit.
Correct a research motion value for zero and axis direction.
When to use this tool
Use Research Motion Measurement Offset when checking the stated effect-size, measurement or interval convention.
How to use the tool and how it works
- Enter recorded, suppliedInstrumentZero, suppliedAxisSign, reference. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read corrected, residual. Use the output convention below.
Correct a research motion value for zero and axis direction. Require suppliedAxisSign +1 or -1; corrected = (recorded-zero)*sign, residual = corrected-reference.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recorded | Recorded | Required. Finite number. |
| suppliedInstrumentZero | Supplied Instrument Zero | Required. Finite number. |
| suppliedAxisSign | Supplied Axis Sign | Required. Safe integer. |
| reference | Reference | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| corrected | Corrected | Required. Finite number. |
| residual | Signed difference in the direction stated above, with matching units. | Required. Finite number. |

}Limitations and assumptions
- Units must match; no instrument calibration, physical motion, treatment effect or clinical meaning is established.
- 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, justified statistical analysis and original study data; distinguish reporting precision from sampling uncertainty and assess clinical relevance independently.
