Using three different panel data sets, the authors show: That mark-ups are significantly higher in South African manufacturing industries than they are in corresponding industries worldwide; That competition policy (i.e. a reduction of markups) should have largely positive effects on productivity growth and employment in South Africa. The paper is...
The study present in this paper investigates the correlation between single-trial evoked brain responses and Galvanic Skin Responses GSR. The correlation between the two signals examined by using a modified principal component regression based approach. A potential application of the study is to utilize the GSR measurements in a form...
There is a small, but growing body of literature highlighting inequities in general medical practitioner GP practice prescribing rates for many drug therapies. The aim of this paper is to further explore the equity of prescribing for five major CHD drug groups and to explain the amount of variation in...
Regression testing is an important part of software quality assurance. The authors work to extend regression testing to include regression benchmarking, which applies benchmarking to detect regressions in performance. Given the specific requirements of regression benchmarking, many contemporary benchmarks are not directly usable in regression benchmarking. To overcome this, the...
Following Hamilton (1989), estimation of Markov regime-switching regressions nearly always relies on the assumption that the latent state variable controlling the regime change is exogenous. One can relax this assumption and develop two techniques to estimate Markov-switching models with endogenous switching. The first extends the endogenous switching models in Maddala...
In this paper, the concepts of correlation and regression are reviewed and demonstrated. The authors review and compare two correlation coefficients, the Pearson correlation coefficient and the Spearman p, for measuring linear and nonlinear relationships between two continuous variables. In the case of measuring the linear relationship between a predictor...
This paper reports a study that examined this assertion more directly through surveying 95 corporate venture units across 3 continents (Europe, South East Asia and North America) and examining the association between their organizational structures, management practices and investment practices, and multiple measures of venture unit performance. Regression analyses found...
This article analyzes the returns distribution of Hedge Funds strategies, the average returns obtained over the past ten years and their correlation with a traditional portfolio. The aim is to identify the characteristics of each Hedge Fund investment strategy in order to be able to construct an optimal Hedge Fund...
Statistical inference in predictive regressions depends critically on the stochastic properties of the posited explanatory variable, in particular, its order of integration. Confidence intervals computed for the largest autoregressive root of many explanatory variables commonly used in predictive regressions, including the dividend yield, the book-to-market ratio, the short-term rate of...
Bank loan syndications have become an increasingly popular and important way for commercial borrowers to satisfy their financing needs. The ability to overcome problems of adverse selection and moral hazard are critical to the development of this market. Using a panel data set constructed from the Shared National Credit Program...
This paper presents a Bayesian technique for the estimation of a logistic regression model including variable selection. The model is used, as in Ou and Penman (1989), to predict the direction of company earnings, one year ahead of time, from a large set of accounting variables from financial statements. It...
This white paper report deals with Hierarchical linear models that are a generalization of Bayesian linear regression. They differ from Bayesian regression in that they determine the width of the prior distribution for the regression coefficients automatically from the data. They are particularly appropriate when we want to answer questions...
This paper describes about key concepts in the planning of airplane manufacturing, the costs of flow time and shows how to quantify these costs; to propose a strategy for flow-time reduction based on productivity improvements from learning. A regression analyses that relate system variances to the direct labor content and...
A musician friend of mine acquired his first iPod recently, and like small boys who don't realise that everyone else went through this about five years ago, he and I frequently discuss our battles with the things. To be fair, though, there is some substance to these conversations, as we...
INTRODUCTION Efficiency frontier analysis has been an important approach of evaluating firms' performance in private and public sectors. There have been many efficiency frontier analysis methods reported in the literature. However, the assumptions made for each of these methods are restrictive. Each of these methodologies has its strength...
Binary logistic regression analyses were performed on institutional data from a large urban community college in order to identify predictors of performance in a content course psychology that had high literacy demands. It was found that students who completed college English were more likely to pass the content course than...
