In this article, we consider the problem of estimation of mode using two-phase sampling. Ratio- and difference-type estimators in two-phase sampling are proposed. The asymptotic properties of the proposed estimators are studied analytically as well as empirically for different situations for the given cost of surveys. The use of two-phase sampling has been found to be cost saving design while estimating mode by making a proper use of auxiliary information. 相似文献

In this article, we consider the problem of estimation of population mean using the known median of auxiliary variable. We proposed an estimator and its efficiency is studied analytically as well as empirically for different conditions. The proposed estimator is found to be more efficient than traditional estimators such as sample mean and linear regression estimator. 相似文献

In this study we attempt to bring attention to the situation of people with disabilities in the developing world by focusing on the labor market of Nepal. Utilizing a unique dataset collected from people with hearing, physical, and visual impairments through questionnaire-based interview methods, we compare across employment based on type of impairments and education levels to identify variation in occupational choices, as well as examining any positive life changes brought by employment. Results indicated that people with hearing, physical or visual impairments often dominated a specific employment sector. Numbers of people with physical, hearing and visual impairments were respectively large in the non-governmental organization sector, restaurants, and local schools. In addition to income, greater social inclusion, respect in the community, more friends, increased confidence, and discovering the new abilities were some of the positive life changes experienced by employees with disabilities. 相似文献
