Primes¶
- Identifiability
- In statistics and econometrics it appears as parameter identifiability in structural-equation models, the rank-and-order conditions for simultaneous-equation systems, identification of causal effects via instrumental variables or regression discontinuity, and weak-identification problems where parameters are technically identified but practically not.
This sourceSurvey cataloguing identification concepts in econometrics — point versus set, structural-equation rank-and-order conditions, instrumental variables, weak identification.
Supported in partVerified against the publisher's abstract
Lewbel's abstract catalogues over two dozen identification terms in econometrics, including weak identification, and contrasts structural with causal/reduced-form models — but it names no rank-order conditions, IV, or RD.
“Over two dozen different terms for identification appear in the econometrics literature, including set identification, causal identification, local identification, generic identification, weak identification, identification at infinity, and many more.”
- In statistics and econometrics it appears as parameter identifiability in structural-equation models, the rank-and-order conditions for simultaneous-equation systems, identification of causal effects via instrumental variables or regression discontinuity, and weak-identification problems where parameters are technically identified but practically not.
- Preimage
- This is the structural content of econometric identification, parameter identifiability in statistics, and case-closing in forensics.
This sourceSurveys identification as whether the mapping from parameters to observables is invertible (the preimage a singleton).
Supported in partVerified against the publisher's abstract
Lewbel's abstract covers identification inside econometrics only, so it backs the econometric half of the sentence and neither the statistics nor the forensics half.
“gives a new framework unifying existing definitions of point identification”
- This is the structural content of econometric identification, parameter identifiability in statistics, and case-closing in forensics.
Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 2 of 2 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
