Combining Nonexchangeable Functional or Survival Data Sources in Oncology Using Generalized Mixture Commensurate Priors.
Conventional approaches to statistical inference preclude structures that facilitate incorporation of supplemental information acquired from similar circumstances. For example, the analysis of data obtained using perfusion computed tomography to characterize functional imaging biomarkers in cancerous regions of the liver can benefit from partially informative data collected concurrently in non-...
متن کاملExplaining Heterogeneity in Risk Preferences Using a Finite Mixture Model
This paper studies the effect of the space (distance) between lotteries' outcomes on risk-taking behavior and the shape of estimated utility and probability weighting functions. Previously investigated experimental data shows a significant space effect in the gain domain. As compared to low spaced lotteries, high spaced lotteries are associated with higher risk aversion for high probabilities o...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Bayesian sample size calculations in phase II clinical trials using a mixture of informative priors.
A number of researchers have discussed phase II clinical trials from a Bayesian perspective. A recent article by Mayo and Gajewski focuses on sample size calculations, which they determine by specifying an informative prior distribution and then calculating a posterior probability that the true response will exceed a prespecified target. In this article, we extend these sample size calculations...
متن کاملData-driven articulatory inversion incorporating articulator priors
Recovering the motions of speech articulators from the acoustic speech signal has a long history, starting from the observation that a simple concatenated tube model is a reasonable model for the origin of formant resonances. In this work, we take a different approach making minimal assumptions about the interdependence of acoustics and articulators by estimating the full joint distribution of ...
