Efficient estimation of population variance of a sensitive variable using a new scrambling response model [PDF]
This study introduces a pioneering scrambling response model tailored for handling sensitive variables. Subsequently, a generalized estimator for variance estimation, relying on two auxiliary information sources, is developed following this novel model ...

A Survey Design for a Sensitive Binary Variable Correlated with Another Nonsensitive Binary Variable [PDF]
Tian et al. (2007) introduced a so-called hidden sensitivity model for evaluating the association of two sensitive questions with binary outcomes. However, in practice, we sometimes need to assess the association between one sensitive binary variable (e ...

A generalized class of estimators for sensitive variable in the presence of measurement error and non-response. [PDF]
In this paper, a general class of estimators is proposed for estimating the finite population mean for sensitive variable, in the presence of measurement error and non-response in simple random sampling.

Calibrated-Two Optional Randomized Response Techniques (C-TORRT) for the estimation of quantitative sensitive variable information. [PDF]
Accurate estimation of sensitive quantitative variables remains a challenge in survey research due to respondents' reluctance to disclose truthful information. While existing randomized response techniques (RRT) offer privacy protection, many suffer from

An efficient estimator of population variance of a sensitive variable with a new randomized response technique [PDF]
In sampling theory, a majority of the available estimators of population variance are designed for use with non-sensitive variables only. Such estimators cannot perform efficiently when the variable of interest is of sensitive nature, such as use of ...

Scrambling Reports: New Estimators for Estimating the Population Mean of Sensitive Variables
Warner proposed a methodology called randomized response techniques, which, through the random scrambling of sensitive variables, allows the non-response rate to be reduced and the response bias to be diminished. In this document, we present a randomized

Advances in Estimation of Sensitive Issues on Successive Occasions
Surveys related to sensitive issues are accompanied with social desirability response bias which flaw the validity of analysis. This problem became serious when sensitive issues are estimated on successive occasions.

Cost-Sensitive Variable Selection for Multi-Class Imbalanced Datasets Using Bayesian Networks
Multi-class classification in imbalanced datasets is a challenging problem. In these cases, common validation metrics (such as accuracy or recall) are often not suitable.

Inferring the Population Mean with Second-Order Information in Online Social Networks
With the increasing use of online social networking platforms, online surveys are widely used in many fields, e.g., public health, business and sociology, to collect samples and to infer the population characteristics through self-reported data of ...
