Anonymous polls nowadays rely solely on centralization, which means that respondents should trust the owner's company not to share responses or look through all submitted answers. However, there is a concept of randomized response trades need for with some error. In this paper, classical forced protocol extended by using an arbitrary random variable. We try optimize tradeoff between accuracy an...

This paper applies Kim and Warde’s (2004) stratified Warner’s randomized response model to Mangat and Singh’s (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Warde’s (2004) and Mangat and Singh’s (1990) estimators...

SUMMARY Chronic low back pain (CLBP) is challenging to treat with its significant psychological and cognitive behavioural element involved. Mindfulness meditation helps alter the behavioural response in chronic pain situations. Significant body of research in the filed of mindfulness meditation comes from the work of Dr Kabat-Zinn. The current evidence in the field, though not grade one, shows ...

The present investigation considers the problem of estimating the mean of a sensitive quantitative variable μA in a human population survey, using the scrambled response technique suggested by Ryu, Kim, Heo and Park (On stratified randomized response sampling, Model Assisted Statistics and Application 1(1), 31–36, 2005–2006). Specifically, using the prior estimate (or guessed mean) of the mean ...

BACKGROUND Hepatic resection is still associated with significant morbidity. Although the period of parenchymal transection presents a crucial step during the operation, uncertainty persists regarding the optimal technique of transection. It was the aim of the present randomized controlled trial to evaluate the efficacy and safety of hepatic resection using the technique of stapler hepatectomy ...

Analytical solutions are attractive for parametric studies and consideration of the problems physics. In addition, analytical solutions can be employed as a reference framewo...

In the previous lecture we introduced a streaming algorithm for estimating the frequency moment F2. The algorithm used very little space, logarithmic in the length of the stream, provided we could store a random function h : {1, . . . , n} → {±1} “for free” in memory. In general this would require n bits of memory, one for each value of the function. However, observe that our analysis used the ...
