Finding new valuable sampling points and making these better distributed in the design space is key to determining approximate effect of Kriging. To this end, a high-precision Kriging modeling method based on hybrid criteria (HKM-HS) proposed solve problem. In HKM-HS method, two infilling strategies MSE (Mean Square Error) are optimized obtain candidate points. By maximizing (MMSE) model, it ca...

In 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.
