Efficient Moments-Based Permutation Tests: A Framework, Methods and Applications
… only assumption for permutation tests is data exchangeability. In real applications, the data exchangeability condition is not always valid. In order to preserve the exchangeability condition required in permutation tests, we propose a new blockwise permutation test approach based on the …

Resource Exchanges in Dyadic Family Relations in the u.s. And Japan: Towards a Theory of Dependence and Indepenence of the Elderly (United States)
… study attempted (1) to identify and compare the exchangeability of six interpersonal resources: money, goods, services, status, love and information in American and Japanese family relationships, (2) to isolate exchange rules distinctive to each system, and (3) to examine the relationship between …

Bayesian Dynamic Data Borrowing Methodologies for Source-Specific Inference
… inference in a primary source. Multisource exchangeability models (MEM) have been introduced as such a dynamic data borrowing approach, determining the amount of information to borrow based on the exchangeability between the primary and supplemental sources, where exchangeability is defined …

Subjective Probabilities in Choice Experiments' Design: Three Essays
… of subjective probabilities elicited via the Exchangeability Method, an innovative elicitation mechanism which consists of several chained questions. Here, validity is investigated using de Finettiâ€ÂTMs notion of coherence under which subjective probabilities are coherent if and only if …

Morphometrics, molecular ecology and multivariate environmental niche define the evolutionary history of the Western Rattlesnake (Crotalus viridis) complex
… that quantified ‘historical’ and ‘recent’ non-exchangeability among lineages and subspecies (i.e., if these entities were distinct amongst themselves and worthy of taxonomic recognition). In this regard, sufficient genetic, ecological and morphological non-exchangeability exists between …

Computability, inference and modeling in probabilistic programming
… in the presence of additional structure like exchangeability and noise, both of which are common in Bayesian hierarchical modeling. This theoretical work bears on the development of probabilistic programming languages (which enable the specification of complex probabilistic models) and their …

Latent variable model estimation via collaborative filtering
… which arises from the natural property of "exchangeability", i.e. invariance under relabeling of the dataset. The analysis suggests that similarity based collaborative filtering can be viewed as kernel regression for latent variable models, where the features are not directly observed and …

From Theory to Practice: Improving Causal Conclusions from Healthcare Data
… often unverifiable assumptions, including exchangeability, parallel trends, and correct model specification. Violations of these assumptions can bias treatment effect estimates, making it essential to assess the sensitivity of causal conclusions--particularly in healthcare applications, …

Exchange relations between Fijians and Euro-Americans (1774-1854), with reference to museum collections
… Fiji-‐West early transactions, as well as the exchangeability of their objects. Especially, attention is called to the political agencies, material values and intellectual representations at stake between 1774 and 1854, projected onto objects from both sides of the exchanges. The first section …

Maximum empirical likelihood estimation in U-statistics based general estimating equations
… antipodal symmetry, coordinatewise symmetry and exchangeability. We employ the jackknife empirical likelihood for vector U-statistics to incorporate side information. We use estimated constraint functions and allow the number of constraints and the dimension to grow with the sample size so that …

Geographic and Social Space in Latent Factor Models - Four Essays
… violating assumptions of independence and exchangeability. While this can be problematic and inhibit the unbiased inference of parameters, it can also be a fruitful source of insights and enhance prediction performance. One class of models that serves to manage or profit from the presence …

Integrative simulation framework for modeling dynamic cellular phenomena in 3D over time
… of the model is designed for the easy exchangeability of data. Furthermore, the integration of cell model file format standards is permitted by exchangeable plug-ins. The implemented system includes an Application Programming Interface (API) for writing individual plug-ins to utilize …

Ecotoxicological Risk Assessment: Developments in PNEC Estimation
… we also discuss the detection of species non- exchangeability, a concept which is recognised by scientists and risk assessors, yet typically discounted in practice. A proposal on incorporating knowledge of a non-exchangeable species for probabilistic estimators is discussed and evaluated. The …

Rare Earth Extraction from Clayey Waste Materials by Alkali Pretreatment
… This finding may partially explain the poor ion exchangeability of REEs in coal-based clays. After subjecting to the proposed NaOH pretreatment technique, the passivated REEs on the surface of clay can be effectively removed. Lastly, the possibility of preconcentrating REEs from a kaolinite …
