Purpose – Seeks to examine the impact of national culture on the importance level students place on ten teaching techniques commonly used by US business instructors. Design/methodology/approach – Undergraduate and MBA business students, including students born in the USA and students born in...

Purpose – Importance performance analysis (IPA) is a technique widely used to assist organisations in developing marketing strategies and improving products or service quality. Many scholars have revised IPA to augment its effectiveness. However, this involves some unknown problems that could...

Purpose – The purpose of this paper is to argue that a stationary-differenced autoregressive (AR) process with lag greater than 1, AR( q 1), has certain properties that are consistent with a fractional Brownian motion (fBm). What the authors are interested in is the investigation of...

Abstract In a strength-stress interference model, we are interested in estimating the structural reliability of a system. Here we present Bayesian procedures to estimate the structural reliability and other relevant parameters when covariates are incorporated in the model. Numerical examples...

Abstract Recently, entropy and extropy-based tests for the uniform distribution have attracted the attention of some researchers. This paper proposes nonparametric entropy and extropy estimators based on progressive type-II censoring and investigates their properties and behavior. Performance of...

Summary One problem in statistics is to determine the distributions of estimators and statistics. For distributions of the continuous type the density function of an estimator can at each point be expressed as a multiple integral, but the standard methods for computing integrals are not...

Summary The occurrence of scientific fraud damages the credibility of science. An instrument to discover deceit was proposed with Benford’s law, a distribution which describes the probability of significant digits in many empirical observations. If Benford-distributed digits are expected and...

Summary Several nonlinear time series models have been proposed in the literature to explain various empirical nonlinear features of many observed financial and economic time series. One model that has gained much attention is the so-called self-exciting threshold autoregressive (SETAR) model....

Summary This paper examines the predictive power of different estimation approaches for reservation wages. It applies stochastic frontier models for employed persons and the approach from Kiefer and Neumann (1979b) for unemployed persons. Furthermore, the question of whether or not reservation...

Purpose – Many modern businesses have accommodation needs which vary sharply over time. Corporate real estate (CRE) managers plan for these variations using “common sense” estimates based on average occupation levels, and these estimates are almost always wrong. This study aims to present...
