Mutual Fund industry plays a pivotal role in optimal allocation and channelization of available idle resources in the economy. This role becomes much stronger in the developing economies like Pakistan where the prospective investors do not have much investment knowledge, information, and facilities to invest in the capital markets neither they have risk aptitude for direct investments in risky ...

Meta-analysis is now commonly used in medical research. However there are statistical issues relating to the subject that require investigation and some are considered here, from both a methodological and a practical perspective. Each of the fixed effect and the random effects models for meta-analysis are based on certain assumptions and the validity of these is investigated. A formal test of t...

Based on the Q-function, the conditional expectation of the logarithm of the jointlikelihood between responses and random effects, we propose a case-deletion approach to identify influential subjects and influential observations in linear mixed models. The models considered here are very broad in the sense that any covariance structures can be specified in the covariance matrices of the random ...

Investing in research and development spending (R&D) affects total factor productivity (TFP).Recently new theories of economic growth have emphasized the relationship between R&D and TFPand also identified a number of channels through which a country’s R&D affects TFP of its tradepartner. This study seeks to estimate the effect of agricultural R&D and education spending and someother factors on...

This article investigates the influence of cross-diffusion on the viscous fluid flow over a porous sheet stretching exponentially by applying the convective thermal conditions. Velocity slip at the boundary is considered. The numerical solutions to the governing equations are evaluated using successive linearisation procedure and Chebyshev collocation method. It is observed from this study that...

Background: We had previously identified the genes involved in squamous cell carcinoma of the head and neck using differential display and DNA microarray techniques. We also reported the first analytical study on a novel human gene called LOC92912, which was identified by differential display as a gene up-regulated in such carcinomas. LOC92912, which is a putative member of the E2 ubiquitin con...

The paper presents a real-time physically based simulation of object damage and motion due to a blast wave impact. An improved connected voxel model is used to represent the objects. The paper also explores auxiliary visual effects caused by the blast wave that increase visual believability without being rigorously physically based or computation-

Refrigerator ownership in rural China increased from 14% to 45% over the period 2001-2010.We test the impact on demand for food, particularly meat, using fixed-effect and demand system approaches based on provincial data. Results suggest that rising refrigerator ownership had a negative effect on rural at-home meat demand.

In this paper we derive asymptotic tests for general linear hypotheses on variance components using repeated variance components models In two examples the two way nested classi cation model and the two way crossed classi cation model with interaction we explicitly investigate the properties of the asymptotic tests in small sample sizes
