Variance-mean mixture of the multivariate skew normal distribution

Arslan, Olcay - In: Statistical Papers 56 (2015) 2, pp. 353-378

In this paper, we introduce a new class of multivariate distributions as an extension of the normal variance–mean mixture distributions class. The new class results from a variance-mean mixture of the skew normal and the generalized inverse Gaussian distributions. The new class is very...

On Zenga and Bonferroni curves

Arnold, Barry - In: METRON 73 (2015) 1, pp. 25-30

Three alternative inequality curves are considered as competitors of the classical Lorenz curve as descriptors of income inequality. The Bonferroni curve and the Zenga-07 curve appear to be essentially equivalent to the Lorenz curve. They each determine the parent distribution up to scale...

The half-normal specification for the two-tier stochastic frontier model

Papadopoulos, Alecos - In: Journal of Productivity Analysis 43 (2015) 2, pp. 225-230

In the context of the two-tier stochastic frontier model, we present a new closed-form stochastic specification, the half-normal one. Expressions to calculate average and conditional measures of inefficiency are provided, for regression specifications in levels and in logs. Some results related...

Enhancing prioritisation of technical attributes in quality function deployment

Iqbal, Zafar; Grigg, Nigel Peter; Govindaraju, K.; … - In: International Journal of Productivity and Performance … 64 (2015) 3, pp. 398-415

Purpose – Quality function deployment (QFD) is a planning methodology to improve products, services and their associated processes by ensuring that the voice of the customer has been effectively deployed through specified and prioritised technical attributes (TAs). The purpose of this paper is...

Application and limitation of axiomatic design complexity in quality engineering

Sharma, Naresh K.; Cudney, Elizabeth A. - In: International Journal of Quality & Reliability Management 32 (2015) 1, pp. 3-17

for a system following normal distribution is unbounded and approximate. The purpose of this paper is to present a … systems, a system performing with a uniform distribution and a system performing on target according to a normal distribution … solution for complexity for a normal distribution based on the existing assumptions was given which includes bias in addition …
