Schur-convexity of 2nd order, certain subclass of multivariate arrangement increasing functions with applications in statistics
Revyakov, Mikhail - In: Journal of Multivariate Analysis 116 (2013) C, pp. 25-34
It is shown that starting with a certain meaningful problem of the type “ranking of populations”, a need arises to employ functions which we call “Schur-convex of 2nd order with respect to two variables”. These functions L(v1,v2,v3,…,vn) are symmetric, and they are characterized in...

An alternative to the Weibull step‐stress model
Khamis, Imad H.; Higgins, James J. - In: International Journal of Quality & Reliability Management 16 (1999) 2, pp. 158-165
An alternative is proposed to the Weibull cumulative exposure model in step‐stress testing, that we call the transformed exponential model. The proposed model comes from a natural transformation of the exponential cumulative exposure model. It is as flexible as the cumulative exposure model...

An Approach to the Evaluation of Management Training Exercises
Evans, W.A.; Sculli, D. - In: Leadership & Organization Development Journal 7 (1986) 1, pp. 7-9
Many lower‐level management jobs do not allow managerial talent to manifest itself. Management training exercises are required to identify and develop this talent. These exercises are invariably handicapped by participants providing what they think is the required response rather than their...

Intraday volume and volatility relations with and without public news
Darrat, A.; Zhong, M.; Cheng, L. - 2007
This paper reexamines the dynamic relation between intraday trading volume and return volatility of large and small NYSE stocks in two partitioned samples, with and without identifiable public news. We argue that the sequential information arrival hypothesis (SIAH) can be tested only in periods...

The effect of transaction costs on the decision to replace 'off-the-shelf' software: The role of software diffusion and infusion
Castner, G.; Ferguson, C. - 2000
This study examines the extent to which software diffusion and infusion affect the decision to replace 'off-the-shelf' software, using the example of spreadsheet software. Transaction cost economics motivates the propositions that higher levels of software diffusion and higher levels of software...
