Local Polynomial Regression Estimator of the Finite Population Total under Stratified Random Sampling: A Model-Based Approach Open
In this paper, auxiliary information is used to determine an estimator of finite population total using nonparametric regression under stratified random sampling. To achieve this, a model-based approach is adopted by making use of the loca…

Longitudinal Survey, Nonmonotone, Nonresponse, Imputation, Nonparametric Regression Open
The study focuses on the imputation for the longitudinal survey data which often has nonignorable nonrespondents. Local linear regression is used to impute the missing values and then the estimation of the time-dependent finite populations…
