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...

This paper shows how a great philosopher, like Popper, can easily fall back to a common superstitious person. This paper also criticizes the general practice by statisticians to invent ad hoc method or manipulate data to suppress errors. Instead, this paper promotes the Xenophanes spirit of...

A simple technique is proposed for increasing the asymptotic efficiency of tests of non-nested hypotheses. The principle is to consider the asymptotic regression of one hypothesis test on another. Under certain conditions this produces a test with a smaller variance under the null hypothesis and...

We take a fresh look at Theil's BLUS residuals and ask why they have gone out of fashion. All our simulation experiments indicate that tests based on BLUS residuals have higher power than those based on the more popular recursive residuals, even in those cases (structural breaks) where intuition...

NOTE: This is a description of the abstract and is not the actual abstract. In-depth modeling of three quite different multivariate nonlinear multiplicative Gaussian-Markovian systems have yielded some insights into the generic benefits to be obtained by application of adaptive simulated...

A modern calculus of multivariate nonlinear multiplicative Gaussian-Markovian systems provides models of many complex systems faithful to their nature, e.g., by not prematurely applying quasi linear approximations for the sole purpose of easing analysis. To handle these complex algebraic...

Philosophy of current knowledge distinguishes facts from values. It maintains that facts areobjective, indisputable, universally verifiable, and do not require to persuade. Since rhetoricis persuasion it is assumed to be deceptive and overlook reality. Therefore, statistics in itscurrent form...

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...
