This paper introduces a new two-parameter lifetime distribution, called the exponential-generalized truncated geometric (EGTG) distribution, by compounding the exponential with the generalized truncated geometric distributions. The new distribution involves two important known distributions,...

In spite of the considerable effort of the work focused on the identification of the conditions and factors favourable to innovation in developing countries, very few contributions concern the analysis of the obstacles impeding or slowing the innovation process and factors affecting their...

This paper documents the relationship between appropriation instruments and the innovation activity in Tunisia. It focuses on the factors that determine the appropriation of innovation activities like the value of sales of the firms, networking, science–industry linkage, competitive pressure...

The relationship between exports and the propensity to innovate is an important issue for a developing economy. This article is dedicated to this question through the analysis of the first innovation survey of Tunisian firms. In particular, it distinguishes the propensity to innovate among three...

This paper introduces a new family of lifetime distributions, using the ascendant order statistics.The proposed distribution is called the exponential-generalized truncated Poisson (EGTP) distribution. Our approach follows the same procedure as Adamidis and Loukas (1998) and generalizes the...

The main purpose of this paper is to classify clients applying for credit into different classes using poisson-mixture approachs which accomodate for heterogeneity and exess-zeros found in the data. This classification permits to determine the optimal interest rate that maximizes bank profit...
