Generalized mixture estimators for the finite population mean | 2016 | 2087 | The first order approximation of the theoretical mean square error and assumption of bivariate normality are very often used for the ratio type estimators for the population mean and variance. We have examined the adequacy of the first order approxim... |

Two-stage Optional Randomized Response Models. | 2008 | 4639 | Social desirability bias (SDB) is defined as a tendency in people to present themselves in a more socially acceptable light, when faced with sensitive questions. People with a higher degree of SDB tend to give answers that will make them look good ra... |

Modified binary randomized response technique models | 2017 | 1386 | Social Desirability Bias (SDB) is the tendency in respondents to answer questions untruthfully in the hope of giving good impression to others. SDB occurs when the survey question is highly sensitive or personal, and responses cause sample statistics... |

Ratio estimation of the mean under RRT models | 2016 | 2969 | Ratio estimation is a parameter estimation technique that uses a known auxiliary variable that is correlated with the study variable. In many situations, the primary variable of interest may be sensitive and it cannot be observed directly. However, w... |

Variations of the Greenberg Unrelated Question binary model | 2018 | 1807 | We explore different variations of the Greenberg Unrelated Question RRT model for a binary response (yes or no). In one variation, we allow m independent responses from each respondent. In another variation, we use inverse sampling where we record th... |

Mean estimation of sensitive variables under measurement errors and non-response | 2020 | 620 | This study mainly consists of three important issues we face in survey sampling: social desirability bias, measurement errors, and non-response. In this dissertation, we study the mean estimation of a sensitive variable under measurement errors and n... |

A two-stage binary optional randomized response model | 2012 | 2934 | Social Desirability Bias (SDB) is the tendency in respondents to answer questions untruthfully in the hope of giving good impression to others. SDB occurs when the survey question is highly sensitive or personal, and responses cause sample statistics... |

Variance estimation using Randomized Response Technique | 2021 | 736 | The aim of this dissertation is to study the problem of variance estimation for sensitive variables. The problem of variance estimation in the non-sensitive variable case has been well-explored by researchers. However, very little attention has been ... |
