Das synthetische Zulässigkeitsregister für Selektionsbias

Jede Zeile nennt eine Aussage zu dieser Abbildung, ihre Quelle und die Art ihrer Prüfung.

• A LR15-C3 Why observational methods fail here is an economics problem, in the authors' words: "The median confidence interval on return on investment is over 100 percentage points wide", so "informative advertising experiments can easily require more than 10 million person-weeks"Lewis & Rao (2015)
• B R09-OWN-C1 Selection bias arises when the mechanism that puts units into the observed or analyzed sample is related to variables relevant to the target questionAuthor framework grounded in LR15-C3
• B R09-OWN-C2 The target population, eligibility rule, observed sample, and conditioning event are different objects and must not be collapsed into one denominatorAuthor framework
• B R09-OWN-C4 Conditioning on a common consequence of exposure and outcome predictors can create collider bias even when the initial variables were not associatedAuthor causal framework
• B R09-OWN-C6 A selection review should name the target, inclusion path, excluded units, selection variables, expected direction if known, and design or sensitivity testAuthor operating framework
• B R09-OWN-C7 The six-row eligibility ledger is synthetic and contains no participant, customer, employee, or company sampleAuthor synthetic object
• B R09-OWN-C9 A changed eligibility rule can change the comparison set and raw rate without proving a change in the underlying outcome processAuthor negative boundary
