Summary Background Overweight and obesity is a global epidemic. Forecasting future trajectories of the epidemic is crucial for providing an evidence base for policy change. In this study, we examine the historical trends of the global, regional, and national prevalence of adult overweight and...

In this paper some new multivariate estimators for two phase sampling has been proposed. The proposed estimators use information on multiple quantitative variables and as well as multiple qualitative variables. Empirical study has been carried out to see the performance of proposed estimator...

The weighted Weibull model is proposed following the method of Azzalini (1985). Basic properties of the distribution; including moments, generating function, hazard rate function and estimation of parameters; have been studied

In this paper psychometric analysis of Depression, Anxiety and Stress among Women living in Wazirabad City has been explored. Cluster sampling technique was used to collect a sample of size 334. For this purpose Urdu version of Depression, Anxiety and Stress (DASS-21) questionnaire was...

Evidence suggests that risk of chronic diseases may be programmed during the foetal and early life of the infant. With high rates of low birthweight coupled with a rapid nutritional transition, low-income countries are facing an epidemic of chronic diseases. Follow-up of a cohort of adults born...

Objectives: The objectives of this study were to see the degree of dependency of Ischemic Heart Disease (I.H.D) on different risk factors and to develop a model to predict the probabilities of I.H.D in various situations. Study Design: This was a retrospective study. Setting: The data was taken...

Almost all available statistical packages are capable of performing Analysis of Variance (ANOVA) from raw data. Some of statistical packages have capability to perform independent sample t-test, and some other tests of significance on summary data, but seldom would you come across a software...

A new estimator for population mean has been proposed in two phase sampling by using information of multiple auxiliary variables. The minimum variance of the proposed estimator has been obtained. Comparison has also been made with some available estimators of two phase sampling

Almost all available statistical packages are capable of performing Multivariate Analysis of Variance (MANOVA) from raw data. Some of statistical packages have capability to perform independent sample t-test, ANOVA and some other tests of significance on summary data, but you come across not...

In study of the statistical packages, simulation from probability distributions is one of the important aspects. This paper is based on simulation study from Bernoulli distribution conducted by various popular statistical packages like R, SAS, Minitab, MS Excel and PASW. The accuracy of...
