Accuracy of estimating the mean from rounded data
Ushakov, Nikolai; Ushakov, Vladimir G. (Peer reviewed; Journal article, 2020)Rounding errors are an important factor in many statistical problems; therefore, statistical analysis of rounded data has recently received growing interest. In this paper we obtain an estimate of accuracy of the sample ... -
Estimation of the second moment based on rounded data
Samsonov, Sergei V.; Ushakov, Nikolai; Ushakov, Vladimir G. (Peer reviewed; Journal article, 2019) -
Moment-based characterizations of the exponential distribution in the class of distributions with monotone hazard rate
Ushakov, Nikolai; Ushakov, Vladimir G. (Journal article; Peer reviewed, 2018)Some new characterizations of the exponential distribution in the class of distributions with monotone hazard rate are obtained. The characterizations are formulated in terms of expectations of order statistics. -
Statistical analysis of rounded data: measurement errors vs rounding errors
Ushakov, Nikolai; Ushakov, Vladimir G. (Journal article; Peer reviewed, 2018)Since data for statistical analysis are always given in a discretized form, observations contain not only measurement errors but also rounding errors which are determined by the discretization step. In this paper we consider ... -
The output streams in the single server queueing system with a head of the line priority
Ushakov, Nikolai; Ushakov, Vladimir G. (Journal article; Peer reviewed, 2019)Изучена однолинейная система массового обслуживания с бесконечным числом мест для ожидания, произвольным распределением времени обслуживания и двумя пуассоновскими входящими потоками требований. Требования первого потока ...
