Robust estimation of the error variance of the ratio estimator
(Egerton Journal of Humanities, Social Sciences and Education, 1999)
Outlier Robustness of the Estimators of Variance of the Ratio Estimator

Robust Variance Estimation by Linearization Techniques for Poverty Indicators
(Southern Africa Mathematical Sciences Association, 2018)
The need for a reliable and equitable means of measuring population disparity and providing guidelines on implementation of policy decisions has necessitated the search for a precise estimating scheme for poverty indicators. ...

(American Journal of Theoretical and Applied Statistics, 2015)
On Estimation of Panel Data Regression Model in the Presence of Endogeneity and Heterogeneity
(International Journal of Mathematics & Computation, 2015)
Nonparametric model assisted model calibrated estimation in two stage survey sampling
(JKUAT Press Ltd, 2007)
Non-response weighting adjustment approach in survey sampling
(JKUAT Press Ltd, 2006)
Non-response problem is an issue of great concern to all the researchers because it pervades almost all survey research. This ultimately creates potential for bias. The higher the non-response rate the greater the bias if ...
Seasonal time series data imputation: comparison between feed forward neural networks and parametric approaches
(JKUAT Press Ltd, 2005)
Missing data in a time series may be an obstacle that may prevents further analysis of the available series either for control, explanations or forecasting. This paper addresses the problem of "‘filling in"' missing data ...
