1. The decision model assumes that purchase decisions do not occur in a vacuum. 2. Thus portfolio optimization can be implemented using a two-moment decision model . 3. Some theorists have developed sophisticated decision models to assist with planning optimal frequency levels. 4. Recently, expected utility theory has been extended to arrive at more behavioral decision models . 5. The purchase of lottery tickets cannot be accounted for by decision models based on expected value maximization. 6. Start with decision making, decision model , decision analysis, decision theory : ) Hope that helps. 7. An alternative to ignoring uncertainty in quantiative decision models is to explicitly encode uncertainty as part of the model. 8. This has allowed for numerous tests of specific decision models from Optimal Foraging Theory to be tested using Ach?data. 9. Multivariate pattern analysis using EEG has suggested that an evidence based perceptual decision model may be applicable to free will decisions. 10. Despite this, a recent study has sought to confirm the applicability of a perceptual decision model to free will decisions.
