3. A Flexible Model for Time Series of Counts with Overdispersion or Underdispersion, Zero-Inflation and Heavy-Tailedness NSTL国家科技图书文献中心

Qian, Lianyong |  Zhu, Fukang -  《Communications in Mathematics and Statistics》 - 2025,13(2) - 431~454 - 共24页

摘要:Time series of counts observed in practice |  often exhibit overdispersion or underdispersion, zero |  inflation and even heavy-tailedness (the tail |  probabilities are non-negligible or decrease very slowly). In |  this article, we propose a more flexible integer
