In simulation we often have to generate correlated random variables by giving a reference intercorrelation matrix, R or Q. The matrix R is positive definite and a valid correlation matrix. The matrix Q may appear to be a correlation matrix but it may be invalid (negative definite). With R(m,m)...

Generalized Wald's method constructs testing procedures having chi-squared limiting distributions from test statistics having singular normal limiting distributions by use of generalized inverses. In this article, the use of two-inverses for that problem is investigated, in order to propose new...

The identification of the out of control variable, or variables, after a multivariate control chart signals, is an appealing subject for many researchers in the last years. In this paper we propose a new method for approaching this problem based on principal components analysis. Theoretical...

Synthesizing the complex phenomenon of “environment” into a single indicator could leads to a loss of information, which inhibit his use as a reference for the resolution of several issues such as, for example, the allocation of resources. On the other hand it allows to represent the overall...

This paper disc;usses socioeconomic mortality differentials in Pakistan on the basis of data collected in 1979 from a nationally representative sample of over lO,OOO households in a survey carried out for the Population, Labour Force and Migration (PLM) project of Pakistan Institute of...

The study utilizes the multivariate analytical tool to describe the relationship that exists between health care financing, health facility utilization and health outcome in Nigeria. The focus of this research was on women who are of child bearing age and who had given birth to at least one...

This paper is in two parts. Part I is essentially a comparison with the results of the Pakistan Fertility Survey(1970-75) and basically a few themes have been thrown up. One is whether the 12-percent decline in fertility claimed by the PFS can be substantiated. The second presents multivariate...

This paper explores factors that influence households’ engagement in pro poor agro enterprises and examines the impacts of such small and medium scale enterprise on households’ poverty reduction. The paper approaches the objective by estimating a multivariate and data censoring analyses on...

This paper is to provide literature review on traditional financial system classification and offer and alternative classification of financial systems. Conventional wisdom holds that there are basically 2 types of financial systems – bank-based and market-based. But modern research points to...

This article proposes empirical tools to account for the role of heterogeneities in the labour matching process, and shows an application to the Andalusian labour market which relies on individual microdata. Firstly, by considering that the labour market is segmented when workers of a specific...
