The central objective of this study is to examine the association between husbands‟ involvement with healthcare decision making and women‟s future intention of using contraceptives. Bangladesh Demographic...

Under-five child malnutrition is an important phenomenon in developing countries like Bangladesh. Historically certain privileged groups have been benefited by the improvements in economic conditions inflicting health care inequality among the population. This study attempts to examine the association between economic inequality of households and a...

Maternal mortality is an important phenomenon to assess the overall health status of a society. To reduce maternal mortality the worldwide recognized vital three factors are: antenatal care, presence of skilled birth assistance and selection of place of delivery. This study made an initiative to identify potential risk factors which can influence t...

Individual heterogeneity in capture probabilities and time dependence are fundamentally important for estimating the closed animal population parameters in capture-recapture studies. A generalized estimating equations (GEE) approach accounts for linear correlation among capture-recapture occasions, and individual heterogeneity in capture probabilit...

The estimation of animal population parameters, such as capture probability, population size, or population density, is an important issue in many ecological applications. Capture–recapture data may be considered as repeated observations that are often correlated over time. If these correlations are not taken into account then parameter estimates m...

Modeling individual heterogeneity in capture probabilities has been one of the most challenging tasks in capture–recapture studies. Heterogeneity in capture probabilities can be modeled as a function of individual covariates, but correlation structure among capture occasions should be taking into account. A proposed generalized estimating equations...

A set of environmental variables from the river Padma were regressed in a stepwise fashion against the dependent variables phytoplankton standing crops, dominance and species diversity. Multiple variable interactions, as measured by multiple correlation coefficients yielded higher values for the coefficients obtained by regressing individual enviro...

This paper uses the data of Household Income and Expenditure Survey (HIES) 2005 to estimate the determinants of earnings and selection into labor market in Bangladesh. We deal with the selection bias in earnings by using a maximum likelihood system of equations, and a multinomial selection approach is used modeling for selection into the labor mark...

Heterogeneity in capture probabilities represents a serious problem when estimating population size in capture-recapture studies. A generalized estimating equations (GEE) approach is applied to data from a capture-recapture experiment to model capture probabilities through a logit-link function of the covariates. The model accounts for heterogeneit...

Estimation of animal population parameters is an important issue in ecological statistics. Many estimation methods have been developed for the capture-recapture closed population models (Otis et al., 1978; Amstrup et al., 2005). Development of capture-recapture models dealing with individual heterogeneity in capture probabilities has been one of th...

Modeling heterogeneity in capture probabilities is a critical issue when estimating animal abundance from capture-recapture data. Capture-recapture data are collected on the same individuals across successive points in time; i.e., the outcome variable is measured on the same individual at several occasions. Thus, in a capture-recapture study, obser...

Maternal and child health issues continue to be at the forefront of national and global health policies. Notwithstanding the national and global policy initiatives, maternal mortality continues to be on the ascendancy in developing countries. This paper investigates the determinants of institutional delivery among a cross section of Bangladeshi wom...

Health is universally regarded as an important index of human development. Improvements in health would translate into higher incomes, higher economic growth and accelerated declines of poverty. Without understanding the factors which play an important role in health care utilization, efforts to promote demand for health care will not offer a pragm...

During the last decades, a vertical exploration of statistical methodology in the ground of longitudinal data has been observed. One of the most exciting developments in this area is the Generalized Estimating Equation (GEE). This is a widely used approach that does not require the complete specification of the joint distribution of repeated measur...

This paper uses the data of Household Income and Expenditure Survey 2005, a nationally representative sample of 10,080 households in Bangladesh from January, 2005 to December, 2005, to investigate the determinants of illness, choice of health care provider and household out-of-pocket health care expenditures. Three models were used in this paper- l...

The basic focus of this paper is to see how the households try to make their; consumption level smooth and for that purpose what sorts of strategies are undertaken. In fact, the data analysis of the paper is based on the flood affected rural households of Bangladesh during 1998-1999. So the paper measures the extent to which of these households are...

Chemical and biological features of Buragauranga river estuary stretching about eight kilometers beside Rangabali of Galachipa Upozilla, Patüakhali district, Bangladesh showed that the water of the estuary was moderately alkaline (pH 7.8 - 8.21). Conductivity had moderate to very strong and perfect significant correlations (at 5% level) with the ch...

The empirical literature detailing the mechanisms underlying schooling and earnings is limited in the context of Nepal, a country characterized by low enrollment rates and education levels, high illiteracy and a large disparity between male and female education. This paper employed standard Mincercan earning function method to estimate returns to e...

This paper employs the prospective data on maternal morbidity in rural Bangladesh to identify the potential risk factors associated with pregnancy related complications. The data were collected by the Bangladesh Institute of Research for Promotion of Essential and Reproductive Health and Technologies (BIRPERHT) during November, 1992 to December, 19...

The maternal morbidity data in Bangladesh is scanty. In this paper an attempt is made to identify the possible risks of occurring delivery complications among the rural women of Bangladesh in relation to their selected delivery characteristics.

A kappa-like classification statistic is used for assessing the fit of GEE regression models with a categorical response. The statistic is a summary measure depicting how well categorical responses are predicted from the fitted GEE model. The statistic takes on a value of 1 if prediction is perfect and a value of 0 if the fitted model fares no bett...

Analysis of data with repeated measures is often accomplished through the use of Generalized Estimating Equations (GEE) methodology. Although methods exist for assessing the adequacy of the fitted models for uncorrelated data with likelihood methods, it is not appropriate to use these methods for models fitted with GEE methodology. Barnhart and Wil...

This study focused for estimating the parameters of marginal model for repeated binary responses through the Generalized Estimating Equations (GEE) methodology. The GEE were applied to observe how certain covariates relate to change of the disease status overtime. In addition, we focused on the methodology of GEE using conditional and unconditional...

Longitudinal studies are undertaken in the health sciences due to their richness and flexibility in analyzing various types of data. In a longitudinal study the subjects are observed for a specific period of time and information about them are gathered relating to an event of concern at different time points. The repeated observations arising from...
