Surveys such as medical, social science, etc conducted by human are often challenged by
problem of non-response or missing observations. Different imputation strategies have been …

In this paper, we have proposed a regression-type compromised imputation methods free of
unknown parameters. The properties (biases and MSEs) of the proposed class of estimators …

Some e cient product type exponential imputation methods are proposed in this article to
tackle the problem of incomplete values in sampling theory. To investigate the effectiveness …

In this paper, some compromised exponential ratio type imputation methods have been
suggested and their corresponding point estimators have been proposed in simple random …

In this article, we have suggested new methods of ratio exponential type imputation and
proposed their corresponding point estimators to deal with the problems of non-response in …

The crux of this study is to propose some modified and improved compromised imputation
methods and their corresponding point estimators to estimate the population mean using …

Many communication problems may appear during requirements elicitation causing that
final products do not accomplish client expectations. This paper analyzes the impact of using …

The missing data often create nuisance to the survey practitioners in producing the reliable
estimates of the desired parameters. Keeping this point in view, the present work suggests …

Twenty exponential type estimators with imputation have been suggested to overcome the
problem of missing data for a study variable in sample surveys. It has been shown that the …

In this paper, an attempt has been made in proposing some improved estimators of finite
population variance when random non-response is present in the study variable, on the …
