"Evidence Synthesis in Healthcare - a Bayesian belief networks (BBNs) are graphical tools for reasoning with uncertainties. In BBNs, uncertain events are represented as nodes and their relationships as links, with missing links indicating conditional independence. BBNs perform belief updating when new information becomes available; they can handle incomplete information and capture expert judgments along with data. BBNs provide a normative framework for synthesizing uncertain evidence.

Bayesian belief networks (BBNs) are graphical tools for reasoning with uncertainties (see Chap. 7). They can be used to combine expert knowledge with hard data and making sense of uncertain evidence. The computation of Bayesian inference is complex. In this chapter, we provide a step-to-step guide of how to construct and use Bayesian networks by using Netica software.

Bayesian networks (BNs) are graphical tools of reasoning with uncertainties. In recent years,BNs have been increasingly recognized for their capacity to represent probabilistic dependencies explicitly and intuitively, handle incomplete information, and capture expert judgments along with hard data. In this chapter, we examine the underlying logic of BNs and discuss their applications.

Ni Z, 2010, Contrast effects on sequence assessments - a thesis, London School of Economics
Loewenstein and his colleagues found divergent preferences for outcomes assessed in isolation versus those embedded in a sequence, i.e. discounting isolated future outcomes versus preferences for increasing and constant sequences. They also found long intervals (i.e. the difference between time delays) rather than long time delays (i.e. the temporal distance from the present) had a detrimental effect on preference for improvement. This thesis proposes a descriptive model of sequence preferences, namely the contrasts model, which acknowledges the difference between interval and delay. The idea is that delay and interval are two different kinds of variables. Delay is non-relational and describes characteristics of individual outcomes, whereas interval is relational and describes characteristics of outcomes in relation to one another. Built on this idea, the contrasts model assumes that the value of a sequence consists of a non-relational part (the endowment value), which is a function of delay and nominal value of the component outcomes and a relational part (the contrast value), which is a function of the signed value difference between the outcomes, their interval and domain relatedness (i.e. whether or not the outcomes share the same domain). Delay and interval influence the endowment and the contrast respectively. Empirical investigations provide evidence for the contrasts model. Decision makers are capable of distinguishing between influences of delay and interval even when the two coincide and exert conflicting influences. Experiments using both money and non-monetary outcomes also show that preferences for improvement can be made more pronounced by shortening intervals and/or enhancing relatedness between the outcomes.
