    • Estimating a Finite Population Total using a Density Function 

      Jakperik, Dioggban; Otieno, Romanus Odhiambo; Okungu, Jacob Oketch (Eurasian Bulletin of Mathematics, 2021-05-02)
      An improved method for finite population total estimation is proposed using a multiplicative semi-parametric bias reduction density function. The density is first applied to estimate a non-parametric regression model which ...

    • Inference on poverty indicators for Ghana 

      Jakperik, Dioggban; Otieno, Romanus Odhiambo; Orwa, George Otieno (2018-09-14)
      Poverty indicators are the fundamental statistics used to optimally determine the standards of living of people in any country. These are used for policy planing and analysis. Poverty indicators were estimated using ...

    • Robust Variance Estimation by Linearization Techniques for Poverty Indicators 

      Jakperik, Dioggban; Otieno, Romanus Odhiambo; Otieno, George (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. ...

    • A SEMI-PARAMETRIC MULTIPLICATIVE BIAS REDUCTION DENSITY WITH A PARAMETRIC START 

      Jakperik, Dioggban; Otieno, Romanus Odhiambo; Orwa, George Otieno (Pushpa Publishing House, 2018)
      In this study, a multiplicative semiparametric fourth order bias reduction density is proposed. The proposed density accommodates all parametric distributions and produces optimum results even in situations where the ...

    • Variance Estimation for Poverty Indicators via Linearization Technique 

      Jakperik, Dioggban; Otieno, Romanus Odhiambo; Orwa, George Otieno (2018-08-24)
      In this study, an assessment of precision of poverty indicators is made with a view to improving its performance. A multiplicative bias reduction density function is used in estimating the poverty indicators and compared ...
