A Resonant Response to Random Excitation
SIAM Journal on Applied Mathematics, 1979Let $Ly = f$ where L is an ordinary differential expression with real constant coefficients and f is a stationary random function. The asymptotic behavior of the correlation function $\langle {y(s)y(t)} \rangle $ is found for s and t large when L has undamped resonances.

A Controlled Randomized Response Technique
Evaluation & the Health Professions, 1993The randomized response survey technique appears to be suitable for studies of sensitive sexual behaviors, particularly inAIDS-related research. However, existing methods provide only estimates of group statistics, not of individual information. Additionally, the popular "unrelated question" approach requires the knowledge of the parameters of the ...

Optimal Randomized Response Models
International Statistical Review / Revue Internationale de Statistique, 1976Summary Randomized response methods allow different kinds and degrees of privacy depending upon models and parameters. A theoretical approach to efficiency is suggested based on minimizing variance for given privacy requirements. Privacy requirements are indexed by measures from information theory, variances are expressed in terms of these measures ...

A New Model for Randomized Response
International Statistical Review / Revue Internationale de Statistique, 1973In sample surveys it is often difficult to get reliable information from the respondents. This is very often the case when the investigation deals with phenomena that are illegal or looked upon as morally condemnable by society. As, for example, illegal abortion and withholding incomes at self-assessment.

Randomized Response Techniques: A Review
Statistica Neerlandica, 1987Randomized response techniques (RRT) are well–known as tools to procure trustworthy survey data on confidential issues. A review is attempted here of mostly published accounts on RRT covering qualitative and quantitative characters. Conflicting criteria of efficient estimation and protection of privacy are discussed.

Logistic Randomized Response Model
2009Sensitive topics or highly personal questions are often faced in medical psychological and socio-economic survey. Warner’s pioneering randomized response (RR) device, as a method for reducing evasive answer bias while estimating the proportion of people in a community bearing a sensitive attribute, has been studied extensively over the last four ...

On an example of a randomized response model
Model Assisted Statistics and Applications, 2015Here we consider an interesting example of a randomized response model and see how diverse statistical techniques can be used in estimating parametric functions of a sensitive variable. We compare the suggested estimator under the proposed model to some well known estimators, including Warner's celebrated estimator.

Randomized Response Techniques
2021Generally, in surveys the randomization is done for the selection of the sample from a population for the estimation of some population parameters like population mean or total or proportion, ratios like birth or death rate, population correlation coefficient or regression coefficient, etc.

On stratified randomized response sampling
Model Assisted Statistics and Applications, 2005In this paper, we propose a new quantitative randomized response model based on Mangat and Singh [7] two-stage randomized response model. We derive the estimator of the sensitive variable mean, and show that our method is more efficient than other randomized response models suggested by Greenberg et al. [3] and Gupta et al. [4] estimators.

Nonparametric response‐adaptive randomization for continuous responses
Pharmaceutical Statistics, 2018Many response‐adaptive randomization procedures have been proposed and studied over the past few decades. However, most of these procedures are based on parametric structure and do not directly apply to nonparametric models. In this paper, we propose a response‐adaptive randomization procedure based on Mann‐Whitney U test statistic.
