    Estimation of a Finite Population Mean under Random Nonresponse Using Kernel Weights by Nelson Kiprono Bii, Christopher Ouma Onyango, John Odhiambo

    Published 2020-01-01
    “…Regression models have been recognized as one of the techniques of reducing bias and variance due to random nonresponse using auxiliary data. In this study, it is assumed that random nonresponse occurs in the survey variable in the second stage of cluster sampling, assuming full auxiliary information is available throughout. …”
