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...

Very large data sets in economics are already available and will soon become commonplace. The econometric techniques currently in use may not be relevant and new techniques will have to be devised. It can be argued that most tests of significance, linear models, assumptions of normality, and...

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...

I comment on the controversy between McCloskey & Ziliak and Hoover & Siegler on statistical versus economic significance, in the March 2008 issue of the Journal of Economic Methodology. I argue that while McCloskey & Ziliak are right in emphasizing 'real error', i.e. non-sampling error that...

For statistical process control, a number of single charts that jointly monitor both process mean and variability recently have been developed. For quality control-related hypothesis testing, however, there has been little analogous development of joint mean-variance tests: only one two-sample...

Yitzhaki (1996) showed that the OLS estimator of the slope coefficient in a simple regression is a weighted average of the slopes delineated by adjacent observations. The weights depend only on the distribution of the independent variable. In this paper I demonstrate that equal weights can only...

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...
