Missing observations in regression: a conditional approach [PDF]
Royal Society Open Science, 2023 This note presents an alternative to multiple imputation and other approaches to regression analysis in the presence of missing covariate data. Our recommendation, based on factorial and fractional factorial arrangements, is more faithful to ancillarity ...

On the joint volatility dynamics in international dairy commodity markets. [PDF]
Aust J Agric Resour Econ, 2021 The present study investigates the price (co)volatility of four dairy commodities—skim milk powder, whole milk powder, butter, and cheddar cheese—in three major dairy markets. It uses a multivariate factor stochastic volatility model for estimating the time‐varying covariance and correlation matrices by imposing a low‐dimensional latent dynamic factor ...

Elucidating the foundations of statistical inference with 2 x 2 tables. [PDF]
PLoS ONE, 2015 To many, the foundations of statistical inference are cryptic and irrelevant to routine statistical practice. The analysis of 2 x 2 contingency tables, omnipresent in the scientific literature, is a case in point.

Relationships Between Self-Esteem and Personal Attributes, Income, Consumption, and Assets: Japanese Panel Study [PDF]
European Journal of Investigation in Health, Psychology and EducationSelf-esteem is a key topic in psychology and health research. It influences well-being, happiness, and even medicine. However, existing studies on self-esteem have yielded conflicting results, suggesting that a global consensus remains elusive.

Combining Statistical Evidence When Evidence Is Measured by Relative Belief [PDF]
EntropyThe problem of combining statistical evidence concerning an unknown, contained in each of the k Bayesian inference bases, is discussed. This can be considered as being related to the problem of pooling k priors to determine a consensus prior, but the ...

Stronger social bonds do not always predict greater longevity in a gregarious primate. [PDF]
Ecol Evol, 2018 We categorized adult female blue monkeys according to the strength and consistency over time of their closest social ties. Females that had strong but inconsistent ties had a higher risk of death than females in all other categories. Social dominance rank, group size, and life history strategies did not influence mortality.

Ignorability, Sufficiency and Ancillarity
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1997 Summary This paper explores the relationship between ignorability, sufficiency and ancillarity in the coarse data model of Heitjan and Rubin. Bayes or likelihood ignorability has a natural relationship to sufficiency, and frequentist ignorability an analogous relationship to ancillarity.

A Second-Order Investigation of Asymptotic Ancillarity
Annals of Statistics, 1985 The paper deals with approximate ancillarity as discussed by \textit{B. Efron} and \textit{D. V. Hinkley} [Biometrika 65, 457-487 (1978; Zbl 0401.62002)]. In the multivariate i.i.d. case the second-order Edgeworth expansion of the MLE given a normalized version of the second derivative of the log-likelihood at its maximum is derived, which is a ...

On the Concepts of Sufficiency and Ancillarity in the Presence of Nuisance Parameters
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1975 Summary Examples are presented to show how ambiguities may arise from attempts to define and apply analogues of sufficiency and ancillarity in the presence of nuisance parameters. It is necessary to tread with caution if one wishes to avoid inconsistencies or unexpected consequences inherent in principles which, on first acquaintance ...
