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...

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...

Trade liberalization effects on commodity imports in Cameroon
Emmanuel Tambi, N. - In: Journal of Economic Studies 25 (1998) 3, pp. 193-202
The hypotheses that an increase in relative price elasticities is not associated with increased import substitution and that an increase in income and foreign exchange elasticities is not associated with a greater degree of “openness” of the Cameroon economy are investigated using...

SEM being more effective than multiple regression in parsimonious model testing for management development research
Cheng, Eddie W.L. - In: Journal of Management Development 20 (2001) 7, pp. 650-667
Aims to commend SEM (structural equation modeling) that excels beyond multiple regression, which is a popular statistical technique to test the relationships of independent and dependent variables, in expanding the explanatory ability and statistical efficiency for parsimonious model testing...
