Description
Calculate one supplied instrument-times-structural-residual moment term.
Econometric calculations separate supplied residuals, regressors, weights, restrictions, panel groups and reference periods. One score or moment contribution is not a fitted estimator, and one scalar covariance term is not a standard error. Unit rescaling and event-time arithmetic preserve conventions without establishing model identification or causal interpretation.
Calculate one supplied instrument-times-structural-residual moment term.
When to use this tool
Use Instrument Exclusion Moment Row when you already have instrumentValue, structuralResidual and need to calculate one supplied instrument-times-structural-residual moment term.
How to use the tool and how it works
- Enter instrumentValue, structuralResidual. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read momentContribution. Use the output convention below.
Return instrumentValue*structuralResidual with signs preserved.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| instrumentValue | Instrument Value | Required. Finite number. |
| structuralResidual | Structural Residual | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| momentContribution | Moment Contribution | Required. Finite number. |

}Limitations and assumptions
- No sample moment is aggregated, exclusion restriction tested, instrument validated or structural model estimated.
- 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
Fit and evaluate the full specified model with appropriate data, grouping and uncertainty treatment for inference. Aggregate the required score/moment terms and use the complete covariance calculation; a local residual, cutoff flag or supplied coefficient transformation does not validate the estimator.
