Credibility Evaluation Of Hardware-In-The-Loop Simulation Test For Guided Weapons, Jianbin Dou, Xiaobing Wang, Bin Shan, Zhang Yan
Credibility Evaluation Of Hardware-In-The-Loop Simulation Test For Guided Weapons, Jianbin Dou, Xiaobing Wang, Bin Shan, Zhang Yan
Journal of System Simulation
Abstract: The thesis explained the concept of credibility evaluation of hardware-in-the-loop simulation. The models and the processes were introduced in three parts: credibility evaluation of simulation system, monitoring of simulation test process, and credibility evaluation of simulation results. The credibility evaluation model of hardware-in-the-loop simulation system was built based on TOPSIS and the credibility evaluation model of simulation results was built based on simulation and firing practace. This way could answer the credibility of hardware-in-the-loop simulation, and provide strong support for hardware-in-the-loop simulation in guided weapons test and evaluation.
Sequential Estimation By Intervals Of A Fixed Width Of The Asymptotic Variance Of Rank Estimates Of The Shift Parameter, Gulnoza Rakhimova
Sequential Estimation By Intervals Of A Fixed Width Of The Asymptotic Variance Of Rank Estimates Of The Shift Parameter, Gulnoza Rakhimova
Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
In this paper, we consider a sequential interval estimation by intervals of a fixed width of the asymptotic variance of rank estimates of the shift parameter. Reviewed the asymptotical properties of estimates of functionals of an unknown probability density and the conditions of the asymptotical consistency of a confidence interval of a fixed width and the asymptotical efficiency of the stopping time. The convergence rate of consistency of the fixed width interval for the asymptotic variance of rank estimates of the shift parameter is obtained.

Robust Confidence Intervals For The Population Mean Alternatives To The Student-T Confidence Interval, Moustafa Omar Ahmed Abu-Shawiesh, Aamir Saghir
Journal of Modern Applied Statistical Methods
In this paper, three robust confidence intervals are proposed as alternatives to the Student‑t confidence interval. The performance of these intervals was compared through a simulation study shows that Qn-t confidence interval performs the best and it is as good as Student’s‑t confidence interval. Real-life data was used for illustration and performing a comparison that support the findings obtained from the simulation study.
Assessing The Accuracy Of Approximate Confidence Intervals Proposed For The Mean Of Poisson Distribution, Alireza Shirvani, Malek Fathizadeh
Assessing The Accuracy Of Approximate Confidence Intervals Proposed For The Mean Of Poisson Distribution, Alireza Shirvani, Malek Fathizadeh
Journal of Modern Applied Statistical Methods
The Poisson distribution is applied as an appropriate standard model to analyze count data. Because this distribution is known as a discrete distribution, representation of accurate confidence intervals for its distribution mean is extremely difficult. Approximate confidence intervals were presented for the Poisson distribution mean. The purpose of this study is to simultaneously compare several confidence intervals presented, according to the average coverage probability and accurate confidence coefficient and the average confidence interval length criteria.
