To some extent, the preventability of the attributable burden is also influenced by its method of estimation (in particular the counterfactual, or reference value, against which the impact of current exposure burden was estimated, or in the case of expert evaluation the formulation of the question; see sections (a) and (b) below).
Since these counterfactuals refer to particular events at particular times, counterfactual theories of causation are theories of singular causation.
In this case, the pairing of the terms corresponds to identity of referents (Bickle 1992: 224) and IN can be directly obtained from TR (the reducing theory), whereas in cases on the opposite point of the spectrum, pairing is achieved only by reference to counterfactual limiting assumptions and boundary conditions.
Counterfactual-based analysis requires reference to a comparison group that allows to estimate how the outcome measure would have changed in the treated population in absence of the intervention [ 42].
By construction, the counterfactual LTU shares for the reference period coincide with the pre-crisis minimum of the actual LTU shares.
The chief obstacle in empiricists' minds to explaining causation in terms of counterfactuals was the obscurity of counterfactuals themselves, owing chiefly to their reference to unactualised possibilities.
The baseline and counterfactual together provide a 'frame of reference' for judging conservation outcomes.
The reference level provides a counterfactual business-as-usual scenario of what future net emissions would be, against which the actual future net emissions can be compared [7, 12, 17].
If we assume the counterfactual retrieval of more than 1000 references from Google Scholar, the following estimates have to be taken into account for a comparison: – How long does it take to 'translate' search expressions between up to 10 different databases for the conventional search?
The first difficulty in assessing counterfactual causal effects is to choose the reference condition when comparing one treatment level t with another treatment level c, that is, the substantive meaning of "treatment c".
