Improving the Estimation Methodology of Monthly Data in Direction of Trade Statistics

Gong, Xiaoning - 2006

The quality of the estimated data in DOTS depends on the availability and accuracy of direction of trade reports and the estimation methodology. Because of the low coverage of monthly reporting, the estimating procedure plays a role of increased importance. This study, however, reveals two...

Discrepancies between Quarterly GDP Estimates

Bloem, Adriaan - 2006

Countries compiling quarterly estimates for gross domestic product (GDP) often use alternative approaches simultaneously. This may result in the publication of different measures of quarterly GDP and discrepancies between these measures. Such discrepancies are unavoidable, unless reconciliation...

Multivariate Monotone Bayesian Updating

Torres, Ricard - 2012

We consider a Bayesian decision problem in which an agent must draw inferences about multiple unobserved variables. This problem appears in different economic settings, for instance in the theory of agency. Assume that both observed and unobserved variables are ordered. We say that the inference...

A Note on the Theory of Applied Statistics

Kenett, Ron S. - 2018

This note is a sketch of what could be the basis for a theory of applied statistics. Such a theory is needed to help … statistics become more relevant, with significant impact and innovative developments. To achieve this goal, statisticians need to … new data structures require new statistical models. Eliciting the components of a theory of applied statistics is a …

Bayesian Comparative Statics

Mekonnen, Teddy - 2020

We study how changes to the informativeness of signals in Bayesian games and single-agent decision problems affect the distribution of equilibrium actions. A more precise private signal about an unknown state of the world leads to an mean-preserving spread of an agent's beliefs. Focusing on...

Visualization and Statistical Modeling of Financial Big Data : Log-Linear Modeling With Skew Error

Jimichi, Masayuki - 2018

In this paper, we consider the visualization and statistical modeling of financial data (e.g., sales, assets) for many global firms which are listed and delisted. This study presents an exploratory data analysis carried out in the R programming language. The results show that a log-linear model...

Statistical Inference in Evolutionary Dynamics

Sawa, Ryoji; Wu, Jiabin - 2021

We introduce evolutionary dynamics for two-action games where agents with diverse preferences use statistical inference to guide their behavior. In each period, agents are randomly selected to revise actions. They draw a random sample of other agents’ actions, use statistical inference to...

Comprehensive OOS Evaluation of Predictive Algorithms with Statistical Decision Theory

Dominitz, Jeff; Manski, Charles F. - National Bureau of Economic Research - 2024

We argue that comprehensive out-of-sample (OOS) evaluation using statistical decision theory (SDT) should replace the current practice of K-fold and Common Task Framework validation in machine learning (ML) research. SDT provides a formal framework for performing comprehensive OOS evaluation...
