SUMMARY:Национален семинар по стохастика
DESCRIPTION:Поредната сбирка на \nНационалния семинар по стохастика\nще се проведе на 21 април 2026 г. (вторник) от 14:00 часа в зала 503 на ИМИ – БАН. \nДоклад на тема \nHow long does it take to train an Elephant Random Walk\nще изнесе \nZheng Fang (University of Zurich). \n\nРезюме: We study how conditioning on the first \(k\) steps\, which we think of as training\, affects the long-term behavior of the Elephant Random Walk. When the elephant is conditioned to be at position \(k\) at time \(k\)\, the first return time to the origin scales as \(k^{(4−4p)⁄(3−4p)}\) in the diffusive regime\, and grows exponentially in the critical regime. We loosely interpret this as a measurement of the rate at which the elephant forgets its training. \nПовече информация за доклада можете да намерите на страницата на семинара: \n\nhttp://www.math.bas.bg/~statlab/NSPS/\n

SUMMARY:Национален семинар по стохастика
DESCRIPTION:Поредната сбирка на \nНационалния семинар по стохастика\nще се проведе на 29 април 2026 г. (сряда) от 14:00 часа в зала 503 на ИМИ – БАН. \nДоклад на тема \nProgressively Type-II censored competing risks data from Odd Lindley Half-Logistic distribution\nще изнесе \nStevo Gjorgiev (Ss. Cyril and Methodius University in Skopje). \n\nРезюме: A competing risks model based on the Odd Lindley Half Logistic distribution is considered under progressive Type II censoring. Maximum likelihood estimates for the distribution parameters are obtained\, and the existence and uniqueness of these estimates are proven. The EM algorithm is applied to solve the log- likelihood equations and construct the s-th EM sequence. Additionally\, using the missing information principle\, the observed and expected Fisher information matrices are derived\, and asymptotic confidence intervals for the parameters are computed based on them. \nПовече информация за доклада можете да намерите на страницата на семинара: \n\nhttp://www.math.bas.bg/~statlab/NSPS/\n
