[ 1 ] - A Consistent Estimator for Uniform Parameter Under Interval Censoring
The censored data are widely used in statistical tests and parameters estimation. In some cases e.g. medical accidents which data are not recorded at the time of occurrence, some methods such as interval censoring are used. In this paper, for a random sample uniformly distributed on the interval (0,θ) the interval censoring have been used. A consistent estimator of θ and some asy...
[ 2 ] - تعمیمی از مدل دلتا شوک
در مدل دلتا شوک، یک سیستم از کار می افتد هر گاه فاصله زمانی بین دو شوک متوالی کمتر از مقدار از پیش تعیین شده ای مانند δ باشد که این سطح بحرانی می تواند به زمان بازیابی سیستم تعبیر شود. در این مقاله، با فرض آنکه سیستم در معرض شوک هایی قرار دارد که در طول زمان بطور تصادفی رخ می‌دهند، تعمیمی از مدل دلتا معرفی می شود. در مدل جدید، مقادیر δ_1 و δ_2 دو سطح بحرانی هستند بطوریکه هرگاه فاصله زمانی بین د...
[ 3 ] - On Conditional Inactivity Time of Failed Components in an (n-k+1)-out-of-n System with Nonidentical Independent Components
In this paper, we study an (n-k+1)-out-of-n system by adopting their components to be statistically independent though nonidentically distributed. By assuming that at least m components at a fixed time have failed while the system is still working, we obtain the mixture representation of survival function for a quantity called the conditional inactivity time of failed components in the system. ...
[ 4 ] - A study on interval estimation in exponential lifetimes under interval censoring
In this study, the interval estimations are proposed for the functions of the parameter in exponential lifetimes, when interval censoring is used. Optimal monitoring time and simulation studies are examined as well as the applicability of the topics.
