Abstract |
|
|
| In this paper the problem of estimating finite population variance under measurement errors is discussed. Some estimators
based on arithmetic mean, geometric mean and harmonic mean under measurement errors are proposed. Biases and mean square errors
of proposed estimators are calculated to the first order of approximation. A comparative study is made among the usual unbiased
estimator, usual ratio estimator and Kadilar and Cingi(2006a) estimator. Hypothetical study is also given at the end of the paper to
support the theoretical findings. |
