Sensitivity analysis bayesian network
Web24 Nov 2024 · Many Bayesian experts (e.g., Muthén and Asparouhov, 2012; Kruschke, 2015) recommend that a sensitivity analysis should always be conducted, and there has even been a checklist developed ( Depaoli and van de Schoot, 2024) that aids in how to conduct and interpret such results in a transparent manner. Web23 Feb 2011 · This is a classic problem of sensitivity analysis that we address in Section 16.3 as it is concerned with controlling network parameters to enforce some constraints on the queries of interest. Assume now that we replace one of the tests with a more accurate one, leading to a new Bayesian network that results from updating the parameters …

Webwww.karger.com Web22 Jun 2014 · We use a Bayesian framework, called the Bayesian analysis of computer code output (BACCO) which is based on using the Gaussian process as an emulator (i.e., an approximation) of complex models/functions. This approach allows effective sensitivity analysis to be achieved by using far smaller numbers of model runs than other methods.
