Making Counterfactual Assumptions
نویسنده
چکیده
This paper provides an update semantics for counterfactual conditionals. It does so by giving a dynamic twist to the ‘Premise Semantics’ for counterfactuals developed in Veltman (1976) and Kratzer (1981). It also offers an alternative solution to the problems with naive Premise Semantics discussed by Angelika Kratzer in ‘Lumps of Thought’ (Kratzer, 1989). Such an alternative is called for given the triviality results presented in Kanazawa et al. (2005, this issue).

On updates with integrity constraints
In his paper “Making Counterfactual Assumptions” Frank Veltman has proposed a new semantics for counterfactual conditionals. It is based on a particular update operation, and we show that it provides a new and interesting way of updating logical databases under integrity constraints which generalizes in particular Winslett’s PMA.
متن کاملModeling Individual Migration Decisions
We summarize recent research that formulates life cycle models of migration which are estimated using longitudinal data. These models consider multiple destinations and multiple periods. The framework offers a unified view applicable to internal and international migration flows, however data limitations severely hinder studies of international migration. As is common in modeling life cycle dec...
متن کاملInductive implementation of segmental HMMs as CS-HMMs
Segmental models have been used in speech recognition to reduce the effect of the counterfactual assumptions of statistical independence which are made in more conventional systems. They have achieved their aim at the cost of a large increase in computational load arising from making assumptions on entire segments rather than on individual frames. In this paper we show how segmental algorithms ...
متن کاملEliciting a Counterfactual Sensitivity Parameter
Sensitivity analyses, wherein estimation is performed for each of a range of values of a sensitivity parameter, are of particular use in causal inference, where estimands often are identified because of untestable assumptions. Sensitivity parameters may have counterfactual interpretations, making their elicitation especially challenging. Here we describe our experience eliciting a counterfactua...
متن کاملA Novel Solution to the Problem of Old Evidence
One of the most troubling and persistent challenges for Bayesian Confirmation Theory is the Problem of Old Evidence (POE, Glymour 1980). The problem arises for anyone who wants to model confirmation and theory appraisal in science by means of Bayesian Conditionalization. This paper addresses the problem as follows: First, I clarify the nature and the varieties of the POE, following Eells (1985,...
