An analytical study of worker well-being and COVID-19 impact using Bayesian panel modeling
This study investigates how the determinants of Japanese workers’ well-being shifted before and during the COVID-19 pandemic. We estimate a Bayesian hierarchical panel model and Markov chain Monte Carlo sampling is implemented with the ancillarity ...

Ancillarity-Sufficiency Interweaving Strategy (ASIS) for Boosting MCMC Estimation of Stochastic Volatility Models [PDF]
Bayesian inference for stochastic volatility models using MCMC methods highly depends on actual parameter values in terms of sampling efficiency. While draws from the posterior utilizing the standard centered parameterization break down when the ...

A note on the determinants of non‐fungible tokens returns
Abstract We aim to identify the determinants of non‐fungible tokens (NFTs) returns. The 10 most popular NFTs based on their price, trading volume, and market capitalisation are examined. Twenty‐three potential drivers of the returns of each NFT are considered.

The concept of sufficiency in conditional frequentist inference
We consider inference about the parameter that determines the distribution of the data. In frequentist inference a very important and useful idea is that data reduction to a sufficient statistic does not lose any information about this parameter. We recall two justifications for this idea in frequentist inference.

When designing a randomized clinical trial to compare two treatments, the sample size required to have desired power with a specified type 1 error depends on the hypothesis testing procedure. With a binary endpoint (e.g., response), the trial results can be displayed in a 2 × 2 table.

A Comment on Affine Invariance and Ancillarity in Testing Multivariate Normality [PDF]
AbstractWith the aim to clarify some confusion apparently still present in part of the literature on testing for multivariate normality, we collect and discuss some facts on invariance and ancillarity of various variants of, so-called, configuration of a multivariate normal sample.
